Fluoride Salts & Specialty Materials We Supply
The product architecture is organized around three practical families: fluoride salts, rare earth salts, and polishing and oxide materials. Each family supports different purity, particle size, and crystal form requirements, which helps engineers select the right grade without over-specifying. Standard products can ship quickly from stock, while custom grades are engineered for applications that need tighter impurity control or a specific particle distribution. This structure helps procurement teams compare materials across suppliers and consolidate orders with one qualified manufacturer. It also gives engineers a clear path from sample evaluation to pilot testing and commercial scale-up. Product data sheets and certificates are available to support incoming inspection and process validation.
Fluoride Salts: Calcium Fluoride, Magnesium Fluoride, Rare Earth Fluorides, Aluminum Fluoride, and Zirconium Fluoride
Fluoride salts form the core of the portfolio and cover industrial, optical, and ultra-high-purity grades. Calcium fluoride is used in optical windows, lenses, and metallurgical fluxes, where clarity and consistency are essential. Magnesium fluoride is valued for UV transparency and durable optical coatings, especially in precision optical systems. Rare earth fluorides support phosphors, catalysts, specialty glass, and advanced ceramic applications. Aluminum fluoride is critical for aluminum smelting and ceramic applications, while zirconium fluoride serves chemical processing and advanced material synthesis. Each grade can be specified by purity, particle size, impurity profile, and crystal form. This flexibility allows buyers to source fluoride salts for routine industrial use or highly controlled optical and electronic processes.
Rare Earth Salts: Nitrates, Acetates, Sulfates, Hydroxides, Chlorides, and Carbonates
Rare earth salts extend the portfolio beyond fluorides and support catalysts, ceramics, glass, and chemical synthesis. Rare earth nitrates are used in catalysts and precursor solutions where solubility and consistent concentration matter. Acetates support homogeneous catalysis and specialty chemical synthesis, while sulfates and chlorides serve glass, ceramic, and metallurgical processes. Hydroxides and carbonates are common intermediates for further processing and are often selected for their handling characteristics. Each salt can be tailored for solubility, particle size, and trace impurity limits to suit the target reaction or formulation. Together, these materials give formulators and manufacturers access to a broad rare earth platform from a single supplier.
Polishing Powders, Zirconium Salts, Aluminum Oxide, and Rare Earth Oxides
Polishing powders, zirconium salts, aluminum oxide, and rare earth oxides complete the advanced materials offering. Cerium-based polishing powders are widely used for precision optical polishing and glass finishing, where surface quality and removal rate must be balanced. Zirconium salts support ceramics, catalysis, and surface treatment formulations, and they are often specified for their chemical stability. Aluminum oxide grades serve abrasives, ceramics, and thermal management applications, with calcination and particle size selected according to the end use. Rare earth oxides are important for phosphors, magnets, catalysts, and polishing media, and they can be supplied in different purity levels. These materials can be matched to specific removal rates, surface finish targets, and slurry chemistries. The result is a coherent portfolio for customers who need both fluoride salts and complementary oxide materials.
General Specifications for Industrial, Optical, and Ultra-High-Purity Fluoride Salts
Specifications are agreed around the application rather than a single catalog number, because a grade that works well in one process may be unsuitable in another. Purity ranges from industrial grade to optical grade and ultra-high-purity grades, depending on the sensitivity of the end use. Particle size can be controlled from coarse crystals to fine micronized powders, and classification can narrow the distribution for polishing or optical applications. Impurity control focuses on elements that affect optical clarity, catalytic activity, electrical performance, or regulatory compliance. Crystal form, bulk density, and moisture content can also be specified when they influence handling or process behavior. The table below summarizes common options, and custom requirements are reviewed by technical staff before quotation.

Applications of Fluoride Salts and Rare Earth Materials
Fluoride salts and rare earth materials appear in demanding applications where small specification differences matter. In optics, calcium fluoride and magnesium fluoride contribute to transmission, coating durability, and thermal stability. In electronics and new energy, high-purity fluorides and rare earth salts support batteries, phosphors, and semiconductor processes. Pharmaceutical and industrial users rely on controlled impurity profiles and consistent particle size to protect yield and product quality. Environmental and aerospace applications use specialty materials in catalysts, coatings, and high-temperature systems. Metal surface polishing benefits from carefully graded oxides and polishing powders that deliver repeatable surface finish.
Optical and Precision Polishing
Optical-grade calcium fluoride is used for windows, lenses, and prisms where low absorption and high transmission are required. Magnesium fluoride is often selected for UV optics and durable anti-reflective coatings because of its favorable optical properties. Precision optical polishing depends on polishing powder chemistry, particle size distribution, and slurry stability, all of which influence surface quality. Rare earth oxides can improve removal rates while maintaining surface quality in glass and optical finishing. Crystal orientation, internal stress, and surface defects are important for demanding optical components. LK supplies optical materials with documentation that supports incoming inspection and process validation.
Electronics, New Energy, and Three-Way Catalysts
High-purity fluoride salts are used in semiconductor cleaning, etching, and specialty glass processes where trace metals must be tightly controlled. Rare earth salts support phosphor production, magnetic materials, and catalyst formulations that depend on consistent chemical behavior. New energy applications include battery precursors and materials for energy storage systems, where purity and particle size affect performance. Three-way catalysts use rare earth oxides and salts to stabilize washcoats and promote oxygen storage, helping meet emissions requirements. Electronic customers require tight control of trace metals and consistent lot-to-lot behavior to avoid process drift. Packaging and handling are designed to protect material quality during global shipment and storage.
Pharmaceutical, Industrial, Environmental, and Aerospace Applications
Pharmaceutical and industrial buyers often need custom purity and particle size rather than a standard grade, because their processes are sensitive to small material changes. Calcium fluoride, magnesium fluoride, and other fluoride salts can be produced within defined impurity limits to support regulated and non-regulated applications. Rare earth acetates, nitrates, and chlorides are used in chemical synthesis and process intermediates, where solubility and reactivity matter. Batch records, COA, TDS, and SDS documents support quality audits and regulatory review. Custom testing can include ICP-MS, XRD, particle size analysis, and loss on drying, depending on the specification. These controls help manufacturers reduce variability and improve yield.
Metal Surface Polishing
Metal surface polishing uses polishing powders and oxides to achieve brightness, scratch removal, and surface uniformity. Aluminum oxide and cerium-based polishing powders are common choices for stainless steel, aluminum, and other metals, and the selection depends on the base material and desired finish. Particle size distribution affects cut rate, scratch depth, and final surface roughness, so classification is an important part of product design. Slurry pH and dispersion stability also influence polishing performance and can affect cycle time. Custom grading helps match the powder to automated or manual polishing lines. LK can supply trial quantities and scale to production volumes for customers developing new polishing processes.
Custom Purity, Particle Size, and Impurity Control
Customization begins with the target specification and the manufacturing process that will use the material. Purity, particle size, impurity content, crystal form, and moisture are reviewed together because they interact in real processes. For optical materials, trace impurities and internal defects can affect transmission and laser damage thresholds. For catalysts and electronics, specific elements must be controlled even at low ppm levels to protect activity and reliability. Production batches are tested against agreed limits before release, and results are documented for traceability. When a standard grade is close but not exact, engineering a custom grade can avoid compromise and reduce downstream variability.
Custom Manufacturing and Batch Testing
The custom manufacturing process starts with raw material selection and process route review. Reaction conditions, purification steps, drying, and milling are adjusted to meet the specification. Particle size reduction and classification can produce narrow distributions for polishing and optical applications. Impurity control may involve precipitation, filtration, washing, or recrystallization, depending on the target element limits. Pilot batches validate the process before commercial production, and scale-up is planned with quality and logistics teams. Each batch is sampled and tested, and results are documented in the COA.
Packaging, Global Shipping, and Export Compliance
Packaging is selected to protect material quality during storage and global shipping, especially for hygroscopic or fine powders. Standard options include moisture-barrier bags, fiber drums, and customized liners, with labels that support warehouse and production control. Labels include product name, grade, batch number, net weight, and handling information. For export, documentation is prepared according to destination requirements, and shipments are coordinated with freight partners. Dual-use export compliance is managed through internal controls and licensing reviews before shipment. Customers can contact theSupport team for shipping and documentation questions.
