Magnesite 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.
As an alkaline refractory material, magnesia brick not only has strong resistance to alkaline slag, but also high refractoriness and refractoriness under load.
Magnesia Bricks Classification:
2. Chemical bonded magnesite brick is made of fused magnesite as the raw material.
