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
將菱鎂礦、水鎂石和由海水或鹵水中提取的氫氧化鎂經800~1000℃左右煅燒,使其分解排出CO2或H2O,即得到輕燒鎂粉,也稱輕燒氧化鎂、苛性氧化鎂或輕燒鎂,俗稱苦土粉。輕燒鎂粉質地疏松、化學活性大,既可以用于制造鎂水泥、菱鎂建材制品、隔熱保溫材料等,又是二步煅燒法生產優質鎂砂的中間產物。
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.
