Corundum brick is a kind of high alumina refractory bricks, and mainly produced and applied as special refractory mateirals in extreme working conditions. Corundum brick is made of high purity fused alumina powder, white fused alumina oxide or tabular alumina, adding with other binders like refractory clays, reactive alumina powder, and high purity silica. Corundum bricks are calcined at high temperatures to form a matrix with mullite, mullite-corundum or corundum, which making corundum brick with excellent volume stability structure and service temperature can be reach to 1900°C.
