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

Description

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.

Chemical Properties

white to light beige powder

Uses

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.

Uses

In the ceramics and glass industry.

Hazard

Strong irritant. TLV: 2.5 mg(F)/m3.

Safety Profile

Moderately toxic by ingestion. When heated to decomposition it emits toxic fumes of F-. See also MAGNESIUM and FLUORIDES.
