Magnesium oxide powder is also known as light burned magnesium powder, light burned magnesium oxide, caustic magnesium oxide or light burned magnesium.
Light burned magnesium is produced by mixing magnesite, magnesium hydroxide and other raw materials, calcined at about 800~1000℃, so that it decomposing and discharging CO2 or H2O.
Light burned magnesium powder is light yellow, light brown powder, specific gravity 3.07~3.22, accumulation density 0.8~1.2g/cm3. The texture is crisp, has the pore structure, the reaction activity is high.
Packaging Detail: 25/50kg PP Bag or 1000kg and 1250kg Jumbo Bag, or as customer’s request.
