Light-burned magnesium is widely used in many fields such as building materials, chemical industry, metallurgy, medicine and so on. It is an ideal material for the production of fire-proof boards, lightweight partition boards, magnesium sulfate, papermaking, desulfurization process, slag splashing in steel plant furnace protection .
Preparation of lightly burned magnesium powder: lightly burned magnesium balls
Calcined magnesite, brucite and magnesium hydroxide extracted from seawater or brine are calcined at about 800-1000 ° C to decompose and discharge CO2 or H2O, to obtain light-burned magnesium powder, also called light-burned magnesium oxide, caustic oxidation Magnesium or lightly burned magnesium, commonly known as bitter earth powder. Light-burned magnesium powder has a loose texture and high chemical activity. It can be used in the manufacture of magnesium cement, magnesite building materials, thermal insulation materials, etc. It is also an intermediate product of two-step calcination to produce high-quality magnesia.
