Detailed description

Light burning Magnesium Oxide

Magnesium Oxide, MgO, is called Magnesium Oxide, commonly known as magnesia magnesia, light burning powder and magnesia powder. Density 2.94, pale yellow or white powder. The melting point is 2852 centigrade, and the boiling point is 3600. It is soluble in acid and ammonium salt, which is difficult to dissolve in water and ethanol. The specific surface area of the calcined temperature at 400 C is 180m2/g. At 1300 C, the specific surface area is only 3m2/g. Easy deliquescence in the air. It belongs to the pneumatic cementation material.

Light burned Magnesium Oxide is also called caustic magnesia, active magnesia. It is a light burned Magnesium Oxide obtained by calcining of Mg (OH) 2, a natural magnesite ore, magnesium Hydrite and magnesium hydroxide extracted from sea water or brine, which is calcined at 700~1000 C.

(1) magnesite ore is one of the main sources of Magnesium Oxide, the content of (MgO) is about 47%, and MgCO3 is calcined by calcined (400~600) calcined (Mgo). The mineral resources are widely distributed in provinces and autonomous regions such as Liaoning, Xinjiang, Sichuan, Shandong and Tibet, with a total reserves of 28 billion tons, accounting for 30% of the world's mineral resources.

(two) dolomite [CaMg (CO3) 2] is also the main source of Magnesium Oxide, and its reserves are more widely distributed and MgO content is about 22%. The content of CaO is about 30%, the rest is 48%, and the two of MgCO3 and CaO's theoretical structure are one to one. The demarcation line of dolomite is based on the content of MgCO3 above 25%, otherwise it can not be used as the ore for producing Magnesium Oxide, nor can it be called dolomite.

(three) serpentine [Mg6 (Si4O10) (OH) 2] is also the raw material for the production of Magnesium Oxide, mainly magnesium silicate (3MgO. 2SiO2 2H2O).

(four) melting slag of light magnesium alloy is also the raw material for producing Magnesium Oxide.
