Naturally occurring CaF 2 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. [11] Hydrogen fluoride is liberated from the mineral by the action of concentrated sulfuric acid: [12]

The application of hexafluorosilicic acid to a calcium-rich surface such as concrete will give that surface some resistance to acid attack. [13] CaCO 3 + H 2 O → Ca 2+ + 2 OH − + CO 2 H 2 SiF 6 → 2 H + + SiF 2− 6 SiF 2− 6 + 2 H 2 O → 6 F − + SiO 2 + 4 H + Ca 2+ + 2 F − → CaF 2. Calcium fluoride (CaF 2) is an insoluble solid ...
Tin(II) fluoride, commonly referred to commercially as stannous fluoride [1] [2] (from Latin stannum, 'tin'), is a chemical compound with the formula SnF 2. It is a colourless solid used as an ingredient in toothpastes .
Boron trifluoride was discovered in 1808 by Joseph Louis Gay-Lussac and Louis Jacques Thénard, who were trying to isolate "fluoric acid" (i.e., hydrofluoric acid) by combining calcium fluoride with vitrified boric acid. The resulting vapours failed to etch glass, so they named it fluoboric gas. [27] [28]
