应用
For plasma spraying, Refractory applications, electrical insulation, pharmaceuticals, cosmetics, paper manufacture, adsorption and catalysis, and in semiconductors, reflector in optical instruments. Magnesium oxide is used as a laboratory reagent and an insulator in industrial cables. It acts as a reference material for calorimetry. It is widely used as a basic refractory material for crucibles, a protective coating in plasma displays, an oxide barrier in spin-tunneling devices, an optical material, a component of tubular construction in heating elements, and also in libraries for preserving books. Magnesium oxide microspheres used in enrichment method of polycyclic aromatic hydrocarbons.

备注
Hygroscopic and a noncombustible substance.
