Light burnt magnesia mainly produces cementitious materials, such as magnesia cement, insulation and sound insulation building materials, as well as ceramic raw materials. After chemical treatment, light burnt magnesia can be made into a variety of magnesium salts, which can be used for medicine, light burnt magnesia ball rubber, man-made fibers, papermaking and other raw materials. Heavy burnt magnesia. Most of the refractories used for metallurgy are used for making magnesia bricks, chrome magnesia bricks, magnesia, metallurgical powder and fused magnesia. It can be used for smelting special alloy steel, lining of medium and high frequency induction furnace for non-ferrous metals and precious metals, magnesium crucible, high temperature electrical insulation material, and light calcined magnesite.

Light-burned magnesia powder is yellowish and light brown powder with particle size below - 100 mesh, small crystal size (< 3 um), true specific gravity 3.07-3.22, bulk density 0.8-1.2 g/cm3, refractive index 1.68-1.70, large lattice constant (a=0.4212) with many lattice defects, brittle texture, porous structure, high reaction activity, easy solid-state reaction or sintering, and hardening with hydrated Mg (OH) 2. Ability. Light-burned magnesia powder calcined from magnesite has a volume shrinkage of about 5%. Usually, there is 3%~5% CO2 left due to incomplete decomposition.
