Light-burned magnesium powder is light yellow light brown powder, the particle size is mostly below -100 mesh. Anshan talc powder periclase crystals are very small (<3μm), true specific gravity is 3.07 ~ 3.22, bulk density is 0.8 ~ 1.2g / cm3. Refractive index of 1.68 ~ 1.70, large lattice constant (α = 0.4212), many lattice defects, crisp texture, pore structure, high reactivity, easy to carry out solid phase reaction sintering, react with water to generate Mg (OH) 2. Hardened adhesive. The light-burned magnesia powder calcined magnesite shrinks about 5% in volume; usually 3% to 5% of CO2 remains due to incomplete decomposition.

Light-burned magnesium is mainly used for the manufacture of cementitious materials, such as magnesium-containing cement. Insulation sound insulation construction materials can also be used as ceramic raw materials. After light-burned magnesium is chemically treated, it can be made into a variety of magnesium salts for use in medicine. Magnesium ball rubber. Man-made fibers. Papermaking other raw materials. Reburned magnesium. Most of the refractory materials used for metallurgy are used to make magnesium bricks. Chrome magnesium bricks. Magnesia. Metallurgical powder. Fused magnesia Smelting special alloy steel, non-ferrous metals precious metals, high frequency induction electric furnace linings, magnesium crucibles, it can also be used as high temperature electrical insulation materials. The source of light burnt powder is calcined magnesite.
