Calciumfluoride superior quality

Chemical properties:
Calcium fluoride is the main component of fluorspar or fluorite, chemical formula CaF2, colorless cubic crystal or white powder. The relative density is 3.18, the melting point is 1423 ° C, and the boiling point is about 2500 ° C. Solubility in water is extremely small, only 0.0016g in 100g water at 18 ℃, insoluble in toluene, degradable chlorine, hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solution, almost no effect with dilute strong acid, with hot concentrated sulfuric acid It forms hydrofluoric acid and forms a complex when it replaces the solution of aluminum salt and iron salt (Fe3 +). Natural calcium fluoride minerals are fluorite or fluorspar, which are often gray, yellow, green, purple and other colors, sometimes colorless, transparent chemical book, with glass luster, brittle, relative density is 3.01 ~ 3.25, there is significant Fluorescence phenomenon. It can be used as a source of fluorine and as a raw material for making hydrofluoric acid and fluoride; it is also used to make glass, enamel, glaze, etc. Metal flux, very pure fluorspar is used to prepare special lenses. When drinking water contains (1 ~ 1.5) × 10-6 calcium fluoride, it can fight dental diseases. Moreover, it is also used in the manufacturing of steel smelting, chemical industry, glass, ceramics. The pure product can be used as a catalyst for dehydration and de-reaction. Calcium fluoride can be prepared by the action of soluble calcium salt (calcium carbonate or calcium hydroxide), hydrofluoric acid or sodium fluoride, and ammonium fluoride.

Application:
Fluorite is the main mineral raw material for the production of fluorine and hydrofluoric acid in the chemical industry. It is also the basic raw material for the production of Freon, fluoropolymers, fluorine-containing fine chemicals, and artificial ice crystal Chemicalbook stones. It is also widely used in metallurgy, cement, glass and ceramics. Colorless and transparent bulk fluorite crystals are aligned with optical fluorite and craft fluorite.
