calcium fluoride usage and synthesis
chemical properties calcium fluoride is the main ingredient of fluorspar or fluorite, the chemical formula is caf2, it is colorless cubic crystal or white powder. the relative density is 3.18, the melting point is 1423℃, boiling point is about 2500 ℃. the solubility in water is minimal , 100g water can dissolve only 0.0016g at 18 ℃, it is insoluble in acetone, but soluble in hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solution, and it can not react with dilute acid, but can react with hot concentrated sulfuric acid and generate hydrofluoric acid, it can form a complex when dissolves in aluminum and iron salts (fe3 +) solution. natural calcium fluoride is mineral fluorite or fluorspar, often shows gray, yellow, green, purple and other colors, sometimes it is colorless, transparent, shiny glass, brittle, and the relative density is 3.01 ~ 3.25, it has significant phenomenon of fluorescence. it can be used as the source of fluorine and the material to make hydrofluoric acid system, fluoride; and it can also be used in terms of the manufacture of glass, enamel, glaze. fluorite is mainly used as a flux in metallurgy, the very pure fluorspar can be used to make specialty lenses. water when contains (1 ~ 1.5) × 10-6 calcium fluoride can prevent dental problems. in addition, it can be used in smelting iron and steel, chemicals, glass, ceramics manufacturing. pure product can be used for catalyst of dehydration, dehydrogenation. by the effect of soluble calcium salts (calcium carbonate or calcium hydroxide) and sodium fluoride or hydrofluoric acid, ammonium fluoride, calcium fluoride can be obtained.
solubility in water (g / 100ml) grams dissolve in per 100 ml of water:8.575×10-3 / 30 ℃
application uses: it is used as the flux of metallurgical, and catalysts of dehydration and dehydrogenation, it can also be used in electronics, instrumentation industry uses: it is used to make hydrofluoric acid and fluoride, and it can also be used for enamel, ceramic and metallurgical flux. uses: it is widely used in chemical industry, metallurgy, glass, enamel and cement and other fields. uses: it is used to make optical glass, optical fiber, enamel, medicine, and it can also be used for catalyst of dehydration and dehydrogenation. uses: fluorite is the main mineral raw materials in the preparation of fluorine and hydrofluoric acid in chemical industry, and it is also the basic raw material for the production of freon, fluorine polymers, fluorine-containing fine chemicals, synthetic cryolite. it is also used in metallurgy, cement, glass and ceramics sectors large amount. the colorless transparent fluorite crystals can be used as bulk optical fluorite and fluorite process. uses: it is widely used in chemical industry, metallurgy, glass, enamel and cement and other fields.
