Magnesium fluoride is compound, halogen fluorine and magnesium metal elements, also known as two magnesium fluoride, molecular formula MgF2, molecular weight is 62.3018.

A colorless tetragonal crystal or powder that is unodorless and insoluble in water and alcohol, slightly soluble in dilute acid and soluble in nitric acid.

Magnesium fluoride (MgF2) is a colorless tetragonal crystal or powder, rutile lattice. Insipid, difficult to dissolve in water and alcohol, slightly soluble in dilute acid, soluble in nitric acid. The relative density is 3.18, the melting point is 1248, and the boiling point is 2260. It has a weak purple fluorescence under electrooptic heating, and its crystal has a good polarization effect, especially suitable for ultraviolet and infrared spectra. Toxic.

purpose
