Product Details

Magnesium fluoride CAS#7783-40-6

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.

Product Application of Magnesium fluoride CAS#7783-40-6

In Mg metallurgy and in the ceramics industry, Magnesium fluoride is used as a flux. Single crystals of alkaline-earth fluorides, such as Magnesium fluoride, are suitable for optical applications because of their large domain of transparency from the ultraviolet to the middle infrared region. Infrared transparent windows may be prepared by hot-pressing Magnesium fluoride powder.
Ternary intercalation compounds of graphite with fluorine and Magnesium fluoride have been prepared; these compounds have high electrical conductivity and would therefore have an important potential as cathodes or new electroconductive materials. Finally, the eutectic NaF–MgF2 has been proposed in advanced latent-heat energy storage for solar power systems.
