Calcium fluoride (chemical formula: CaF2) is a fluoride of calcium, white crystal, insoluble in water, single crystal is transparent. It is the main component of fluorite minerals, but also the main source of fluorine, can be used to produce hydrogen fluoride, fluorine gas, fluoride and other important chemical reagents, the annual output of 500,000 tons (late 1990s). Calcium fluoride type structure is an important structure in crystal structure. In a cubic cell, Ca2+ coordinates with eight F? in cubic form, and F? coordinates with four Ca2+ in tetrahedral form. Due to the presence of F-centers in the crystal lattice, calcium fluoride in minerals is often deeply colored. Hydrogen fluoride is produced from calcium fluoride both in industry and in laboratory. When calcium fluoride reacts with concentrated sulfuric acid in a lead dish, hydrogen fluoride gas is released:
CaF2(s) + H2SO4(l) → CaSO4(s) + 2 HF(g)
Hydrogen fluoride is a very important intermediate in chemical industry, which can be used to prepare hydrofluoric acid, and is also the raw material for producing organofluorine compounds, fluoride and other chemical reagents.
