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

Magnesium Fluoride is used as a flux in magnesium metallurgy and in the ceramics industry. Its single crystals are ideal for optical applications due to their wide transparency range from ultraviolet to mid-infrared, and infrared-transparent windows can be produced by hot-pressing Magnesium Fluoride powder.

Additionally, ternary graphite intercalation compounds with fluorine and Magnesium Fluoride exhibit high electrical conductivity, offering potential as cathodes or novel conductive materials. The NaF–MgF₂ eutectic has also been explored for advanced latent-heat energy storage in solar power systems.
