Calcium fluoride is the inorganic compound of the elements calcium and fluorine with the formula CaF 2. It is a white solid that is practically insoluble in water. It occurs as the mineral fluorite (also called fluorspar), which is often deeply coloured owing to impurities.
Calcium(I) fluoride is an unstable inorganic chemical compound with the chemical formula CaF. It can exist as a high temperature gas, or an isolated molecule in a solid noble gas matrix. It can exist as a high temperature gas, or an isolated molecule in a solid noble gas matrix.

Fluoride (/ ˈ f l ʊər aɪ d, ˈ f l ɔːr-/) [3] is an inorganic, monatomic anion of fluorine, with the chemical formula F − (also written [F] −), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless.
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 ...
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]
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 .
