Use of light burned powder (light burned magnesium powder)

Magnesite calcined at the temperature of 750-1100 is called "light calcined", and its product is called light calcined magnesium powder, which is called light calcined powder for short. Light burned powder is mainly used to manufacture cementitious materials, building materials for heat insulation and sound insulation, and can also be used as ceramic raw materials.

Since the burning loss of magnesite is generally about 50%, the content of MgO in the ore can be almost doubled by light burning. In this sense, light burning is the most effective method for enrichment of MgO. In addition, light burning is also a preparatory operation for thermal separation and some gravity separation of magnesite. Light burned magnesium has high activity and is an ideal raw material for producing high density magnesite

Light burned magnesium is mainly used to manufacture cementitious materials, such as magnesium containing cement, building materials for heat insulation and sound insulation, and also can be used as ceramic raw materials. After chemical treatment, light burned magnesium can be made into a variety of magnesium salts, which can be used as raw materials for medicine, rubber, man-made fiber, paper making, etc. Heavy burned magnesium is mostly used as refractory materials for metallurgy, It is used to make magnesia bricks, chrome magnesia bricks, magnesia, metallurgical powder and fused magnesia. It is mainly used as the medium and high frequency induction furnace lining and magnesium crucible for smelting special alloy steel, nonferrous metals and precious metals. It can also be used as high-temperature electrical insulation materials. The source of light calcined powder is calcined magnesite.
