Product Description
High purity 90% Al2O3 high alumina refractory brick furnace fused corundum brick

Corundum Brick Description
Corundum Brick is a kind of refractory product with corundum as the main crystal phase and contains over 90% aluminium oxide content. Corundum fire bricks have very high cold crushing strength that can reach up to 340MPa and high apparent initial softening temperature that is over 1700ºC. Corundum refractory brick can be used in blast furnace, hot blast stove, glass furnace and etc.
