Magnesium Fluoride is white or crystalline in appearance with a melting point of 1,261°C, a density of 3.18 g/cc, and a vapor pressure of 10-4 Torr at 1,000°C. The main application of magnesium fluoride is in optics, due to its distinctive transparency over a wide range of wavelengths.
Stanford Advanced Materials supplies various high purity materials, evaporation sources, and crucible liners for both thermal and E-beam evaporation. The evaporation materials include pure metals and alloys, oxides ceramics including rare earth oxides, such as Sc2O3, Y2O3, La2O3 and other ceramics, such as fluorides, nitrides etc.
The materials are used in deposition processes including semiconductor deposition, chemical vapor deposition (CVD) and physical vapor deposition (PVD)and mainly for optics including wear protection, decorative coatings, and displays.
Various shapes, such as tablets, granules, rods and wires are available. Customized forms and quantity are also available upon request. SAM also provides evaporation sources, boats, filaments, crucibles and heaters, and e-beam crucible liners.

Impressed with these so far. Used with sophomore students in a lab experiment that went extremely well!
