Refractory high purity alumina Corundum brick for sale
Alumina Corundum brick is made from high quality fused corundum. With scientific grading and high quality addictive, corundum bricks are shaped under high pressure and fired with high temperature. It has the features of high strength, excellent thermal and erosion resistance, stable chemical performance.
HongTai corundum bricks are widely employed in the field of petrochemical industry and refractory to build the lining of high temperature furnace and firing chamber.
Alumina Corundum bricks are high alumina refractory bricks are made for extreme demands. The alumina content in Corundum Brickscan 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.
Alumina Corundum brick 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 Brickscan 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 Bricksare 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.
