Calcium fluoride CaF2 - PubChem

Calcium fluoride. Occurring in nature as the mineral fluorite or fluorspar. It is the primary source of fluorine and its compounds. Pure calcium fluoride is used as a catalyst in dehydration and dehydrogenation and is used to fluoridate drinking water. (From Merck Index, 11th ed) Medical Subject Headings (MeSH) Calcium difluoride is a calcium salt.

Calcium fluoride - Wikipedia

Naturally occurring CaF2 is the principal source of hydrogen fluoride, a commodity chemical used to produce a wide range of materials. Calcium fluoride in the fluorite state is of significant commercial importance as a fluoride source. Hydrogen fluoride is liberated from the mineral by the action of concentrated sulfuric acid: CaF2 + H2SO4 → CaSO4(solid) + 2 HF
