Industrial, Optical & Ultra-High Purity Fluoride Salts from LK (Hebei) New Materials
LK (Hebei) New Materials Co., Ltd. has spent 26 years assembling one of the broadest material portfolios in the Chinese chemical new materials sector, and that experience is now available to buyers worldwide through a single, dependable fluoride salts supplier relationship. The company researches, manufactures and trades chemical new materials, optical materials, rare earth functional materials, high-end ceramic materials and medical bone materials, so its knowledge base spans laboratories, production floors and cross-border logistics alike. Its catalogue contains more than 60 powder and crystal materials, from industrial grade fluoride salts to ultra-high purity fluoride salts measured in parts per million. Annual export volume reaches 16,000 tons, which means large-scale supply is not a claim printed on a brochure but a routine operating reality. Dual-use export qualification allows the company to handle controlled items correctly rather than learning compliance by trial and error. Buyers also rely on credentials such as AAA credit enterprise, contract-honoring and trustworthy enterprise, quality service integrity enterprise and Customs AEO Advanced Certification. Together these factors make LK a practical long-term partner for companies that treat raw material quality as a production variable rather than a purchasing afterthought.
This guide explains how that portfolio is organized, what distinguishes industrial, optical and ultra-high purity grades, and how engineers and procurement teams can specify the right material the first time. It walks through the fluoride salt family in detail, then widens the view to rare earth nitrates, acetates, sulfates, hydroxides, chlorides and carbonates that frequently appear alongside fluorides in the same formulation. It also covers polishing powders, zirconium salts, alumina and rare earth oxides, which together form ten major product categories. Each section focuses on decisions buyers actually face: purity ceilings, particle size distribution, impurity limits, crystal form, packaging and documentation. Where possible, the text explains why a parameter matters in production rather than simply listing it. The goal is to help a technical team shortlist materials quickly and to help a purchasing team ask the right questions before a first order.
Core Fluoride Salt Product Portfolio
The fluoride salt range sits at the centre of the business and covers calcium fluoride, magnesium fluoride, rare earth fluorides, aluminum fluoride and zirconium fluoride. All five families are produced in industrial grade, optical grade and ultra-high purity grade, and all are available as powders, crystals or custom specifications. That combination matters because the same chemical name can serve a cement kiln, a vacuum deposition chamber and a scintillation crystal grower, yet each application tolerates a very different impurity profile. Offering three grades from one source lets customers scale a project from laboratory trial to tonnage supply without changing suppliers or re-qualifying documentation. It also means a single technical contact can advise on trade-offs between cost, performance and availability. The paragraphs below explain what each material is typically used for and where grade selection becomes critical.
Calcium Fluoride (CaF2)
Calcium fluoride is the highest-volume product in the range and appears as both a metallurgical flux and a precision optical material. Industrial grade calcium fluoride powder is used in steelmaking and ferroalloy processing, in cement and ceramics, and as a source of fluorine in chemical synthesis. Optical grade calcium fluoride is grown or sintered into windows and lenses that transmit from the deep ultraviolet through the infrared, which makes it valuable in excimer laser optics and spectroscopy. Ultra-high purity calcium fluoride serves crystal growth and specialty glass where transition metal contamination would cause absorption or scattering losses. Particle size, whiteness and moisture content are controlled independently so a customer can order a free-flowing granular flux or a fine, high-surface-area powder. Because the company controls both crushing and purification steps, grade changes do not require a change of production site.
Magnesium Fluoride (MgF2)
Magnesium fluoride is the material most optical engineers associate with durable anti-reflective coatings and infrared windows. Its low refractive index and wide transparency range make it a standard choice for thin-film deposition in the ultraviolet, visible and infrared bands. The company supplies magnesium fluoride crystal material and high-purity powder suited to evaporation sources, with attention to grain size and residual water because both influence spatter and film uniformity. Optical grade material is screened for metallic impurities that would create absorption centres after deposition. Industrial grade magnesium fluoride also serves aluminium and magnesium metallurgy as an additive that improves melt fluidity and slag behavior. Customers developing coated optics often pair this material with calcium fluoride substrates, which is why both are stocked in compatible grades.
Rare Earth Fluorides
Rare earth fluorides, including lanthanum, cerium, yttrium, neodymium and mixed rare earth varieties, are used in phosphors, crystal growth, optical glass, polishing compositions and catalyst precursors. Purity here directly determines optical yield, because a few parts per million of iron or copper can shift emission color or reduce transparency. The company produces these fluorides with controlled rare earth distribution, meaning a customer can request a specific oxide-to-fluoride ratio or a tightly defined rare earth oxide composition. Crystal growers value consistent particle morphology, since it affects packing density in crucibles and the uniformity of melting behavior. Phosphor manufacturers focus instead on activator-level impurities and on residual moisture that can cause hydrolysis during firing. Both needs are met by adjusting process parameters rather than by selecting a different product line.
Aluminum Fluoride and Zirconium Fluoride
Aluminum fluoride is a primary additive in aluminium electrolysis, where it adjusts bath chemistry and lowers the operating temperature of the cell. Consistent bulk density, flowability and low silica content keep feeding systems stable and reduce fluoride consumption per tonne of metal. Zirconium fluoride supports specialty glass, ceramic and optical applications, and it also acts as a precursor in fluoride glass and coating research. Both materials are offered at industrial and higher purity levels, with impurity specifications agreed at quotation. For aluminium producers, the practical concerns are delivery reliability and moisture control during storage, while for glassmakers it is iron and titanium content. The company addresses these differences through separate screening and packaging routines for each grade.
Across the entire fluoride family, grade is defined by measurable limits rather than a descriptive label. Industrial grade prioritizes consistent bulk chemistry at an economical cost for metallurgy, fluxes and chemical intermediates. Optical grade tightens metallic impurity limits and controls particle size and crystal quality so that transmission and coating performance remain predictable. Ultra-high purity grade targets trace metal levels in the parts-per-million or lower range for crystal growth, phosphors, electronics and analytical reference work. Forms include fine powder, granular material, sintered compact, single crystal and machined optical shapes, and all can be quoted to a custom specification sheet. Documentation packages can include certificates of analysis, batch traceability and, where relevant, dual-use export paperwork. Buyers who need to compare options can review the full listing on the
Products page.
Extended Material Range Beyond Fluorides
Many industrial processes require more than a fluoride, and consolidating those companion materials with one supplier reduces qualification effort considerably. The company therefore also produces rare earth nitrates, acetates, sulfates, hydroxides, chlorides and carbonates, each available in solution or solid form depending on handling preference. Rare earth nitrates and acetates are widely used as catalyst precursors and in metal treatment baths where solubility and clean decomposition matter. Rare earth chlorides serve as intermediates for further conversion, while hydroxides and carbonates are preferred where a low-anion product or a controlled calcination pathway is required. Rare earth oxides complete the chain and are supplied as polishing-grade or high-purity powders with defined particle size. Because the company produces both the fluoride and the oxide of the same rare earth element, customers gain consistency across a multi-material bill of materials.
Beyond the rare earth family, the portfolio includes polishing powders, zirconium salts, alumina and a broad selection of rare earth oxides, bringing the total to ten major product categories. Cerium-based polishing powders are used for precision optical polishing, where removal rate and surface finish depend on particle size distribution and the presence of hard agglomerates. Zirconium salts support ceramics, catalysts and surface treatment, while alumina grades serve ceramics, abrasives, coatings and catalyst supports. Rare earth oxides are essential in phosphors, magnets, glass colorants and three-way catalyst formulations, and each requires its own impurity profile. The practical benefit of this breadth is fewer purchase orders, fewer incoming inspection routines and one accountable technical contact when a formulation changes. Customers can view the combined offering on the
Products page alongside the fluoride range.
Quality Control, Customization and Export Compliance
Customization at LK starts with measurable indicators rather than vague promises, because purity, particle size and impurity content are all adjustable within the production process. A customer can specify a minimum assay, a maximum level for individual elements such as iron, copper or silicon, and a target particle size distribution expressed as D10, D50 and D90. Crystal form, bulk density, moisture content and whiteness can also be tuned where the application is sensitive to them. Each specification is translated into process parameters and confirmed on a certificate of analysis before shipment. Batch consistency is maintained through incoming raw material screening, in-process checks and retained samples that allow a complaint to be traced back to a specific lot. Where a customer needs a genuinely new material rather than a tweak, the technical team can develop it as a joint project.
Export operations are handled with the same discipline, which is a genuine advantage for buyers importing regulated chemicals. The company holds dual-use export qualification and has mature experience in the research, production and cross-border shipment of chemical new materials, optical materials and rare earth functional materials. That means classification, licensing and documentation questions are addressed before goods leave the factory rather than at the port. Packaging options range from sealed foil bags and fibre drums to ton bags, with palletizing and labeling configured for the destination market. Shipping can be arranged by sea, air or express depending on quantity and urgency, and the team is used to coordinating with freight forwarders on hazardous and controlled cargo. Customs AEO Advanced Certification further supports smoother clearance and fewer inspection delays. Buyers who want to discuss a specific lane or document set can do so through the
Support page.
Applications and Industry Use Cases
Few material portfolios span as many sectors as this one, and the application list is a useful way to understand which grade might suit a given project. In industrial manufacturing, fluoride salts work as fluxes, additives and intermediates in metallurgy, glass and chemical synthesis. In pharmaceutical applications, high-purity inorganic salts serve as reagents, intermediates and processing aids where trace metal control is essential. Electronics manufacturing uses fluorides and rare earth oxides in coatings, dielectric layers and thin-film deposition sources. New energy applications rely on high-purity materials for battery precursors, solid-state research and hydrogen-related catalysis. Ternary catalysts for automotive emission control depend on rare earth oxides, carbonates and nitrates with tightly controlled impurity profiles. Environmental protection uses these materials in wastewater treatment, flue gas treatment and catalyst regeneration. Aerospace and defence demand optical-grade fluorides for windows and coatings, while precision optical polishing and metal surface polishing consume polishing powders, alumina and rare earth oxides in large volumes.

Product Selection Guide
Choosing between industrial, optical and ultra-high purity grades is usually a matter of matching impurity tolerance to process sensitivity, and it is worth being deliberate about it. The cheapest grade that meets performance requirements is normally the right answer, because paying for purity that the application cannot detect adds cost without benefit. Where an optical coating fails after deposition, however, the extra cost of optical grade material is trivial compared with a rejected production batch. The following three subsections outline the decision logic, the key parameters to specify and some recommended starting materials for common applications.
Industrial, Optical or Ultra-High Purity Grade
Industrial grade fluoride salts suit metallurgical fluxes, cement and ceramics, chemical intermediates and bulk applications where color and trace metals are secondary to consistent bulk chemistry and price stability. Optical grade is appropriate whenever light must pass through the material or when a deposited film must meet a transmission target, because metallic impurities create absorption and scattering that cannot be corrected downstream. Ultra-high purity grade is the correct choice for crystal growth, phosphors, laser and scintillation materials, electronics and analytical standards, where parts-per-million impurity differences alter performance. A useful rule is to ask what happens if a single impurity doubles, and if the answer involves a failed specification, a higher grade is justified. Buyers should also consider whether the application is regulated, since pharmaceutical and aerospace uses may require additional documentation regardless of grade.
Key Parameters to Specify
Five parameters decide most fluoride salt purchases: assay or purity, particle size distribution, impurity limits, crystal form and application environment. Assay defines how much of the target compound is present, but it says nothing about which impurities remain, so element-specific limits are more informative than a headline percentage. Particle size distribution affects dissolution rate, packing density, flowability in feeders and polishing removal rate, which is why D50 alone is often insufficient. Crystal form influences melting behavior, optical transmission and slurry stability, and it can differ even at identical chemical purity. Application environment covers temperature, humidity, vacuum and contact materials, since hygroscopic powders may need sealed packaging or a drying step before use. Supplying a target specification sheet with these five items usually shortens quotation cycles considerably.
Recommended Materials by Application
For precision optical polishing, cerium-based polishing powders with a controlled coarse fraction and rare earth oxide polishing grades deliver fast removal with minimal surface damage. For catalysis, rare earth nitrates, acetates and carbonates are common precursors, supported by high-purity rare earth oxides for washcoat formulations. For electronics and optical coating, magnesium fluoride and calcium fluoride in optical grade are standard deposition and window materials, complemented by zirconium fluoride for specialty glass. For advanced ceramics, alumina and zirconium salts provide the structural base, while yttrium and other rare earth oxides act as stabilizers. For metallurgy, industrial grade aluminum fluoride and calcium fluoride remain the workhorses. Naming both the material and the target application in an inquiry allows the technical team to propose a specific grade rather than a generic one.

Request Specifications, Samples and Quotations
Most projects begin with a specification rather than a purchase order, and the fastest way to move forward is to send the technical requirement directly to the sales team. Sharing the intended application, target purity, particle size range, annual volume and any documentation needs allows a precise quotation instead of an approximate one. Samples are normally available for qualification testing before a first commercial order, which is particularly useful for optical and ultra-high purity grades. Buyers should mention destination country and port so that packaging, labeling and shipping terms are proposed correctly. Existing customers can also request batch records or a renewed certificate of analysis for retained lots. Use the inquiry form on the
Support page and include the following fields.
- Name and job title
- Business email address
- Company name and country
- Product requirement, including material, grade and specification
- Estimated annual or trial quantity
- Message with application details or documentation needs
Related Products and Internal Links
Buyers often qualify several materials in a single project, so it helps to review the related product families together. Calcium fluoride and magnesium fluoride are the most requested optical and industrial fluorides and are frequently specified on the same purchase order. Rare earth fluorides and rare earth oxides are paired by phosphor, crystal growth and catalyst customers, since the oxide is often the precursor or the polishing counterpart. Polishing powders, zirconium salts and alumina complete the picture for optics, ceramics and surface finishing. Reviewing these families side by side exposes opportunities to consolidate specifications and reduce the number of suppliers a plant must manage. Each product page states the available grades, typical specifications and packaging options.

Frequently Asked Questions (FAQ)
What fluoride salts does this fluoride salts supplier actually manufacture?
The core range covers calcium fluoride, magnesium fluoride, rare earth fluorides, aluminum fluoride and zirconium fluoride. Each family is produced in industrial grade, optical grade and ultra-high purity grade, and each is available as powder, crystal or a custom specification. Beyond fluorides, the same production platform supplies rare earth nitrates, acetates, sulfates, hydroxides, chlorides and carbonates, plus polishing powders, zirconium salts, alumina and rare earth oxides. In total the catalogue contains more than 60 powder and crystal materials across ten major product categories.
Can purity and particle size be customized for a fluoride salts order?
Yes, purity, particle size and impurity content are all adjustable, and customization is treated as normal engineering work rather than an exception. Customers can specify a minimum assay, maximum levels for individual elements such as iron or silicon, and a target distribution expressed as D10, D50 and D90. Crystal form, bulk density and moisture content can also be controlled where the process is sensitive to them. Each agreed specification is confirmed on a certificate of analysis before the shipment leaves the factory.
What is the difference between industrial, optical and ultra-high purity fluoride salts?
Industrial grade prioritizes consistent bulk chemistry and economical cost for metallurgy, fluxes and chemical intermediates. Optical grade tightens metallic impurity limits and controls particle size and crystal quality so that transmission and coating performance stay predictable. Ultra-high purity grade targets trace metals in the parts-per-million range for crystal growth, phosphors, electronics and analytical work. The practical test is to ask what happens if one impurity doubles, and if that would fail a specification, a higher grade is justified.
Which industries use these fluoride salts and rare earth materials?
Applications span industrial manufacturing, pharmaceuticals, electronics, new energy, ternary catalysts, environmental protection, aerospace, precision optical polishing and metal surface polishing. Aluminum producers use aluminum fluoride, steelmakers use calcium fluoride as a flux, and optical coaters rely on magnesium fluoride and calcium fluoride. Catalyst manufacturers consume rare earth nitrates, carbonates and oxides, while ceramics producers source alumina, zirconium salts and polishing powders. This breadth means one technical contact can support a multi-material bill of materials.
Does this fluoride salts supplier support international export and compliance requirements?
Yes, the company holds dual-use export qualification and has mature experience in cross-border trade of chemical new materials, optical materials and rare earth functional materials. Annual export volume reaches 16,000 tons, so documentation, packaging and shipping routines are well established rather than improvised per order. Packaging options include sealed foil bags, fibre drums and ton bags, with palletizing and labeling configured for the destination market. Customs AEO Advanced Certification further supports smoother clearance, and buyers can request a specific document set at quotation stage.
How can customers request samples or a quotation for fluoride salts?
Samples and quotations are requested through the inquiry form on the Support page, ideally with the material, grade, target specification and estimated volume included. Stating the intended application helps the technical team propose a specific grade instead of a generic offer. Destination country and port should also be mentioned so that packaging and shipping terms are correct from the start. Sample qualification is common before a first commercial order, especially for optical and ultra-high purity grades.
How is batch consistency maintained across large production volumes?
Consistency comes from incoming raw material screening, in-process checks and retained samples that allow any complaint to be traced to a specific lot. Process parameters are fixed once a specification is approved, and deviations are investigated before release. Retained samples also let a customer request a renewed certificate of analysis for a previously delivered batch. Because the same site handles both fluorides and their rare earth oxide counterparts, cross-material consistency is easier to preserve than when materials come from separate suppliers.
Are these materials suitable for optical coating and crystal growth applications?
Optical grade magnesium fluoride and calcium fluoride are standard materials for evaporation sources, infrared windows and ultraviolet optics. For crystal growth, ultra-high purity fluorides are supplied with controlled rare earth composition and particle morphology, which affects packing density and melting uniformity in crucibles. Impurity control matters most here because trace metals create absorption or scattering losses that cannot be corrected after growth. Surface finish and crystal form requirements should be stated in the inquiry so the correct grade is quoted.
What documentation is provided with each shipment of fluoride salts?
Standard shipments include a certificate of analysis that reports assay, specified impurity levels and particle size results against the agreed specification. Batch traceability records link the delivered material to production and raw material lots. Where an item is regulated, dual-use export paperwork is prepared in advance rather than at the port. Additional documentation for regulated industries can be discussed during quotation, and packaging lists are provided for customs clearance.
Can several materials be consolidated into one shipment?
Yes, buyers frequently combine fluorides with rare earth compounds, polishing powders or alumina in a single order to reduce freight and inspection overhead. Consolidation is planned during quotation so that packaging, labeling and documentation remain compliant for every item in the container. Mixed shipments also simplify incoming inspection, since one certificate set covers the whole delivery. Customers should confirm the combination early, as some controlled materials require separate handling.
