Description and Uses

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.

Magnesium fluoride (MgF2) is used to polarize corrective lenses of eyeglasses to reduce the glare of sunlight by selecting the orientation of the light waves passing through the lenses. MgF2 is also used to polarize windows, sunglasses, and similar optical items.
