bricks are shaped refractory products with alumina as the main raw material and corundum as the main crystal phase. Corundum bricks have excellent erosion resistance, wear resistance, high temperature strength, load softening temperature, creep and other thermodynamic properties. Corundum bricks have high volume density and good thermodynamic properties, which make them able to resist thermal, chemical and structural damage caused by the operation of gasifiers and other industrial furnaces.

Widely used as lining materials for cracking and conversion furnaces in petrochemical and fertilizer industries, metallurgical industries, residual oil gasifiers, coal gasifiers, carbon black reactors, pulp waste liquid gasifiers and other industrial furnaces.
