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) Calcium difluoride is a calcium saltCalcium fluoride is the inorganic compound of the elements calcium and fluorine with the formula CaF 2 It is a white insoluble solid It occurs as the mineral fluorite (also called fluorspar), Calcium fluoride CaF2 ChemSpiderCalcium Fluorite This is a fun, but useful video in which I make a model of the calcium fluorite crystal structure using oranges and limes The oranges are larger than the limes and so represent the fluorine anions, while the smaller limes represent the calcium cationsDr Scott Ramsay Calcium Fluorite
