Magnesia Bricks Introduction Magnesia Bricks, a kind of basic refractory with more than 90% magnesium oxide content, are made of periclase as the main crystal phase. Magnesia Brick is mainly used in basic open-hearth furnace for steelmaking, electric furnace, rotary cement kiln, heating furnace, glass furnace and hyperthermia tunnel kiln with properties of higher refractoriness, good basic slag erosion resistance and high apparent initial softening temperature. Magnesia Bricks Classification Magnesia Bricks generally can be classified into two types of Burnt Magnesia Bricks and Chemical Bonded Magnesite Brick. 1. Burnt Magnesia Bricks have high purity and firing temperature as the direct contact with periclase crystalline grain. 2. Chemical bonded magnesite brick is made of fused magnesite as the raw material.

Features

Magnesia Bricks Features 1.High refractoriness, usually the refractoriness is above 2000°C. 2.Strong ability to resist basic (alkaline) slag, can not contact with acid refractory material. 3.Strong ability of thermal conductivity, sometime need insulating material. 4.Excellent resistance in slag abrasion,Higher bulk density 5.Lower apparent porosity and Lower impurity content
