Corundum brick is a high-performance refractory material, mainly made of high-purity alumina (Al2O3), with excellent high temperature resistance, corrosion resistance and wear resistance. Its refractoriness can reach above 1800℃, and it has strong thermal shock resistance, which is suitable for use in extreme environments.
Corundum bricks include sintered corundum bricks and fused corundum bricks, which are often used in key parts such as lining, furnace, combustion chamber, etc. of high-temperature kilns in metallurgy, chemical industry, glass and other industries.
