Magnesium fluoride is an inorganic compound with the formula MgF2. The compound is a white crystalline salt and is transparent over a wide range of wavelengths, with commercial uses in optics.
Environmental Effects of Magnesium Fluoride:Exposure to 100% relative humidity at room temperature does not fog polished surfaces even after one month. In normal working conditions, polished surfaces will not degrade. For temperatures exceeding 500°C, magnesium fluoride surfaces will degrade in the presence of moisture. In dry environments, calcium fluoride can be used up to 800°C. Magnesium fluoride is inert to organic chemicals and many acids including HF. It will slowly dissolve in nitric acid.
Magnesium fluoride can be machined with standard diamond tools and water based coolants. The material takes a good polish using either aluminum oxide or diamond based polishing powders using
either pitch or cloth laps.
