Chemie und Industrie
Anwendungen
VerwendenSuitable for vacuum deposition. Magnesium fluoride occurs in nature as the mineral, sellaite. It is used in glass and ceramics. Single crystals are used for polarizing prisms and lenses.
Darstellung
synthetischeMagnesium fluoride is a colorless salt with the rutile structure. It is formed by reaction of magnesium oxide and HF or magnesium carbonate and NH4F·HF. It is also a by product from the manufacture of elements such as beryllium by reduction of the corresponding fluoride by magnesium metal.
