Beschreibung
Magnesium fluoride (MgF2) is a white crystalline salt.
It is used in the electrolysis of aluminum ore to produce
metallic aluminum and also as a reflective coating on
various types of optical components. It is a tetragonal,
birefringent crystal with the TiO2 type of structure.
Chemische Eigenschaften
Magnesium Fluoride is a fine white crystalline powder with low chemical reactivity. This relative inertness makes possible some of its uses, eg, stable permanent films to alter light transmission properties of optical and electronic materials.
Verwenden
Suitable 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.
synthetische
Magnesium 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.
Hazard
Strong irritant. TLV: 2.5 mg(F)/m3.
Sicherheitsprofil
Moderately toxic by
ingestion. When heated to decomposition it
emits toxic fumes of F-. See also
MAGNESIUM and FLUORIDES.
