What is Corundum Brick?

l  Corundum Bricks are high alumina refractory bricks are made for extreme demands. The alumina content in Corundum Bricks can be traced to the use of synthetic corundum of high purity, such as white fused alumina or tabular alumina. Additional ingredients are special refractory clays, reactive alumina and very pure modifications of silica.

l  Corundum Bricks are fired at high temperatures to form a matrix with mullite, mullite-corundum or corundum that has excellent volume stability.

l  The service temperature for Corundum Bricks goes up to 1800°C.

What are the applications of Corundum Brick?

Corundum Bricks can be used nearly all fields of industrial application where extreme high temperature and increased resistance against aggressive slags and atmospheres. Such properties or features of Corundum Bricks are necessary especially in the chemical industry and for the production of carbon black. The addition of chromium oxide, zirconium oxide and phosphates lends the bricks excellent structural flexibility, which is required for ash melting furnaces and gas reactors in incinerators.
