Magnesite is magnesium oxide, which can be made from magnesite, brucite, dolomite, serpentine, olivine and other minerals. Generally, magnesite and brucite can be used as raw materials to calcine and decompose into magnesium oxide, which crystallizes differently due to different calcination temperatures. The magnesium oxide calcined at 600-1000 ℃ is called active magnesium oxide, and the magnesium oxide calcined at 1400-1800 ℃ is called dead burned magnesium oxide. The above two kinds of magnesium oxide are also commonly called light magnesium oxide, commonly known as furnace magnesia.

There are two main specifications of medium grade magnesia, one is 94%, the other is 95%. Medium grade magnesia is mainly used in metallurgy to manufacture metallurgical powder for joining furnace bottom and furnace wall, manufacturing slurry spraying furnace lining, manufacturing magnesium bricks and magnesium chromium bricks. In addition to being used as furnace lining of furnace bottom, it is also widely used in electric steelmaking furnace, heating furnace, non-ferrous metal converting furnace and rotary furnace, It is also a high-quality raw material for producing medium grade magnesia refractory products

High purity magnesite is produced by flotation purification of natural super grade magnesite through light burning, fine grinding, ball pressing and ultra-high temperature oil shaft kiln calcination. It is a high-quality raw material for brick making and indefinite refractory. Medium grade magnesia is produced from light burned magnesia with 97% MgO as raw material by pressing ball and calcining in high temperature shaft kiln. The product has good sintering degree and dense crystallization. It is a high-quality raw material for producing medium grade magnesia refractory products.

With the development of magnesia industry, people pay more and more attention to the use of ordinary fused magnesia, which has become an important product in industrial production. Understanding the use of magnesia is of great significance for better development of magnesia industry. Magnesia is a general term for the products of magnesite and other magnesia raw materials that have been treated at high temperature to reach the degree of sintering. Magnesite fired from natural magnesite by one-step or two-step calcination process with high-temperature equipment such as shaft kiln and rotary kiln is called sintered magnesite
