Chrome Corundum Brick Introduction

Chrome corundum brick is a kind of refractory products with Cr2O3  included. In high temperature, Cr2O3  and Al2O3  form into continuous solid, so the high temperature performance is better than the pure corundum products. The chrome corundum brick used in petrochemical industry gasification furnace should with the properties of low silica, low iron, low alkali, high purity, high density and high strength. The  widely-applied chrome corundum products, the Cr2O3   content is within about 9%~15%.
