Molecule Structure Image



Calcium fluoride is an inorganic compound. This ionic compound of calcium and fluorine occurs naturally as the mineral fluorite. It is the source of most of the world's fluorine. In the laboratory, calcium fluoride is commonly used as a window material for both infrared and ultraviolet wavelengths, since it is transparent in these regions and exhibits extremely low refractive index. Furthermore the material is attacked by few reagents. It is also used as a flux for melting and liquid processing of iron, steel and their composites. Its action is based on its similar melting point to iron, on its ability to dissolve oxides and on its ability to wet oxides and metals.
