Magnesium fluoride represented by the chemical formula MgF2 or F2Mg that bears the IUPAC name magnesium difluoride is a stable compound that is not hygroscopic as such and slightly soluble in dilute acids (like nitric acid) but insoluble in alcohol. It is an ionic compound of magnesium and fluorine and non-polar in gaseous phase [1, 8]. In UV light it fluoresces purple [8].

Magnesium Fluoride Uses

  1. In anti-reflective, multi-layer optical coatings on glass [4].
  2. As a durable material for lenses that can be used in UV and IR light eliminating birefringence [5].
  3. MgF2 windows are widely used in the deep and vacuum UV regions. They are durable and produce minimal aberrations [9].

Is It Dangerous

The compound can be acutely toxic if swallowed. It is a cause of serious eye, skin and respiratory tract irritation. So inhalation should be avoided [7].
