The chrome corundum brick is a corundum refractory brick with Cr2O3. At high temperature, Cr2O3 and Al2O3 form a continuous solid solution, therefor the comparing the pure corundum brick, the chrome corundum brick has better high temperature performance. It is mainly applied in the petrochemical gasifier, in low silicon, low iron, low alkali, high purity,and it also has the high density and strength.
