Definition and Usage Areas of calcium fluoride
The main ingredient of calcium fluoride, fluorspar or fluorite, chemical formula CaF2, is colorless cubic crystal or white powder. The relative density is 3.18, the melting point is 1423 ° C, the boiling point is about 2500 ° C. Solubility in water is small, 100g water only 0.0016g soluble at 18°C, but not soluble in acetone, but soluble in hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solution, and dilute do not react acid but react with hot concentrated sulfuric acid It can form hydrofluoric acid, form complexes when dissolved in aluminum and iron salts (Fe3+) solution.
Naturally occurring CaF 2 is the main source of hydrogen fluoride, a commodity chemical used to manufacture a wide range of materials. Calcium fluoride in the form of fluoride is of significant commercial importance as a source of fluoride.  Hydrogen fluoride gets rid of the mineral under the action of concentrated sulfuric acid.
- Calcium fluoride is used as metallurgical flux and as dehydration and dehydrogenation catalysts,
- It can be used in electronics, instrumentation industry.
- It is used to make hydrofluoric acid and fluoride, and can also be used for enamel, ceramics and metallurgical flux.
- It is widely used in chemical industry, metallurgy, glass, enamel and cement and other fields.
- It is used to make optical glass, optical fiber, enamel, medicine, and can also be used for dehydration and dehydrogenation catalyst.
- Fluorite is the main mineral raw material for the preparation of fluorine and hydrofluoric acid in the chemical industry.
- Freon is the basic raw material for fluorine polymers, fluorine-containing fine chemicals, synthetic cryolite production.
- It is also used in large quantities in the metallurgy, cement, glass and ceramic industries.
- Colorless transparent fluorite crystals can be used as bulk optical fluorite and fluorite process.
