Characteristic
Calcium fluoride is the inorganic compound of the elements calcium and fluorine with the formula CaF2. It is a white insoluble solid. It occurs as the mineral fluorite (also called fluorspar), which is often deeply coloured owing to impurities.
Chemical formula：CaF2
Molar mass：78.075 g·mol−1
Appearance：White crystalline solid (single crystals are transparent)
Density：3.18 g/cm3
Melting point：1,418 °C (2,584 °F; 1,691 K)
Boiling point：2,533 °C (4,591 °F; 2,806 K)
Solubility in water：0.015 g/L (18 °C)
0.016 g/L (20 °C)
Solubility product (Ksp)：3.9 × 10−11
Solubility：insoluble in acetone
slightly soluble in acid
Magnetic susceptibility (χ)：-28.0·10−6 cm3/mol
Refractive index (nD)：1.4338
Crystal structure：cubic crystal system, cF12
Application
Hydrogen fluoride is prepared from calcium fluoride in industry and laboratory.
Hydrogen fluoride is a very important intermediate in chemical industry, which can be used to prepare hydrofluoric acid, organic fluorides, fluorides and other chemical reagents.
