Magnesium fluoride Chemical Properties,Uses,Production

Description

Magnesium fluoride is a by-product of the manufacture of metallic beryllium and uranium. It is a fine white crystalline powder with low chemical reactivity.
Magnesium fluoride is used as flux in magnesium metallurgy and in the ceramics industry. Magnesium fluoride may be used for the extraction of aluminum from arc-furnace alloys with Fe, Si, Ti, and C. Optical windows of highly purified magnesium fluoride which transmit light from the vacuum ultraviolet (140 nm) into the infrared (7) are recommended for use as ultraviolet optical components for the use in space exploration. Magnesium fluoride is can be also used as an antireflection coating material having a good antireflection effect and a low refractive index.

Preparation

Magnesium fluoride is prepared by treating a magnesium salt solution with hydrofluoric acid or sodium fluoride:
MgSO4 + 2HF → MgF2 + 2H+ + SO42–
or by adding hydrofluoric acid to magnesium carbonate:
MgCO3 + 2HF → MgF2 + CO2 + H2O
