Light burned magnesium is widely used in many fields such as building materials, chemical industry, metallurgy, medicine, etc. It is an ideal material for the production of fireproof boards, lightweight partition boards, magnesium sulfate, papermaking, desulfurization processes, and slag splashing in steel mills. .
Preparation of light burnt magnesia powder:
The magnesite, brucite, and magnesium hydroxide extracted from seawater or brine are calcined at about 800~1000℃ to decompose CO2 or H2O to obtain light burnt magnesia powder, also called light burnt magnesia, caustic oxidation Magnesium or light burnt magnesium, commonly known as magnesia powder. Light-burned magnesia powder has a loose texture and high chemical activity. It can be used to manufacture magnesia cement, magnesite building materials, thermal insulation materials, etc., and is an intermediate product for the production of high-quality magnesia by two-step calcination.
