Corundum Bricks Corundum Bricks High Alumina Refractory Bricks Made For Extreme Demands Corundum Bricks are high alumina refractory bricks made for extreme demands. The alumina content in Corundum Bricks is from 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. Corundum Bricks are fired at high temperatures to form a matrix with mullite, mullite-corundum or corundum that has excellent volume stability. The service temperature for Corundum Bricks goes up to 1800°C. Corundum Bricks can be used in nearly all fields of industrial application where extreme high temperature and increased resistance against aggressive slags and atmospheres are necessary. 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 gives the bricks excellent structural flexibility, which is required for ash melting furnaces and gas reactors in incinerators. We distributes Corundum Bricks of the best quality at the most competitive prices with our fast, responsive customer service and reliable delivery service.
