Calcium fluoride powder is a vital inorganic fluoride material, typically appearing as a white, high-purity fine powder. Its exceptional optical properties, chemical stability, and functional characteristics make it indispensable in fields such as optical coatings, specialty glass, high-end coatings, and metallurgical additives.
We specialize in producing and supplying calcium fluoride powder across various purity grades and particle size distributions, offering customized processing tailored to your application requirements. For samples or technical documentation, please contact us at any time.
High purity and optical-grade quality
Precisely adjustable particle size distribution
Excellent chemical and thermal stability
Good dispersibility and batch consistency
Optical Coatings and Crystal Materials: Serves as raw material for vacuum deposition or sputtering in producing anti-reflective coatings, protective films, and UV/IR optical windows. Also functions as a fundamental material for growing laser crystals.
Specialty Glass and Ceramic Manufacturing: Serves as a key fluorine source and modifying additive in formulations for fluorophosphate glass, low-refractive-index glass, and functional ceramics, effectively regulating optical and thermal properties.
High-Performance Coatings and Plastic Fillers: Functionally incorporated into corrosion-resistant coatings, high-temperature coatings, or specialty engineering plastics to enhance coating abrasion resistance, weatherability, and product dimensional stability.
Metallurgical and Welding Auxiliary Materials: Used as a refining agent in special alloy smelting and as a flux component in welding processes, it aids in impurity removal, arc stabilization, and improved weld quality.
Q1: What is the chemical stability of calcium fluoride powder? Is it soluble in water or common acids?
A1: Calcium fluoride is poorly soluble in water and dissolves slowly in cold dilute acids. However, it is soluble in hot concentrated acids or solutions of aluminum and iron salts. It exhibits stable chemical properties under normal conditions and resists corrosion by most organic solvents.
Q2: How does powder particle size specifically impact final applications?
A2: Particle size directly affects surface smoothness in coatings, dispersion uniformity in composites, and reactivity as a precursor. For instance, finer powders typically yield denser, smoother films or coatings.
Q3: How do you ensure the powder remains free from moisture or contamination during transportation and storage?
A3: We employ moisture-proof inner bags with sturdy outer packaging. Customers are advised to store the product in a cool, dry place upon receipt, keeping it sealed and avoiding storage alongside acids or alkalis to maintain its excellent properties over time.
Q4: Can surface-modified calcium fluoride powder be provided to enhance compatibility in organic systems?
A4: Yes. We offer powders surface-treated with coupling agents like silanes or stearic acid, significantly improving wetting and dispersion in polymer matrices, reducing agglomeration, and enhancing the mechanical properties of composite materials.
