The function of light burning powder: magnesite calcined at 750-1100 temperature is called "light burning", and its product is called light burning magnesia powder light burning magnesia. Because magnesite burns down about 50%, the content of MgO in the ore can be almost doubled by light burning. In addition, light burning is also a preparatory operation for magnesite thermal separation and some heavy separation. Light burning magnesia has high activity and is an ideal raw material for producing high-volume and dense magnesia.

Light burnt magnesia mainly produces cementitious materials, such as magnesia cement, insulation and sound insulation building materials, as well as ceramic raw materials. After chemical treatment, light burnt magnesia can be made into a variety of magnesium salts, which can be used as raw materials for medicine, rubber, man-made fibers, papermaking and so on. Heavy burnt magnesia. Most of the refractories used for metallurgy are used to make magnesia bricks and Chrome-Magnesia bricks. Magnesia, metallurgical powder and fused magnesium oxide are mainly used for smelting special alloy steel, lining of medium and high frequency induction furnace for nonferrous and precious metals, magnesium crucible and high temperature electrical insulation material.
