Light burnt powder

Magnesite calcined at a temperature of 750-1100°C is called "light burnt", and its product is called light burnt magnesia powder, or light burnt powder for short. Light burned powder is mainly used to manufacture cementitious materials, heat and sound insulation building materials, and can also be used as ceramic raw materials. 97 fused magnesia

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

Light burned magnesia is mainly used to manufacture cementitious materials, such as magnesium-containing cement. Thermal and sound insulation building materials can also be used as ceramic raw materials. After the light burned magnesium is chemically treated, it can be made into a variety of magnesium salts, which can be used as raw materials for medicine, rubber, man-made fibers, and papermaking. Die-burned magnesia is mostly used as a refractory for metallurgy and used to make magnesia bricks. Chrome magnesia bricks, magnesia sand, metallurgical powder, and fused magnesia are mainly used for smelting special alloy steel. Medium and high frequency induction furnace lining and magnesium crucible for non-ferrous and precious metals. It can also be used as high temperature electrical insulation material. The source of light burned powder is calcined magnesite.
