Magnesite brick is a kind of basic refractory, the content of magnesium oxide is above 90% and the principle crystalline phase is periclase. Generally, it can be divided into the sintered magnsite brick( also named as burnt magnesite brick) and chemical bonded magnesite brick( also named as unfired magnesite brick). The magnesite with high purity and firing temperature, and due to the direct contact of magnesite crystalline grain, it is called as direct-boned magnesite brick; The brick with fused magnesite as main material is called as electrofusion rebonded magnesia brick.

Composition and Properties of Mageisite Bricks
Magnesium block is a kind of magnesium oxide refractory, which contains more than 90% of MgO.
Magnesium brick has the characteristics of high refractoriness, good alkaline slag resistance, erosion resistance, excellent anti-oxidation, high refractoriness under load, high mechanical strength and volume stability at high temperature.
Application of Magnesite Bricks
It is mainly used for steelmaking basic open-hearth, electric furnace bottom and furnace wall, permanent lining of oxygen converter, non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesite brick and cement rotary kiln lining, the bottom and wall of heating furnace, glass kiln regenerator checker brick, etc.
