Corundum & Corundum Mullite Bricks
Corundum & Corundum Mullite Bricks are high alumina refractory bricks for application in extreme conditions. The alumina content is primarily achieved by using pure synthetic types of corundum, such as white corundum and tabular alumina. Special refractory clay, special clay and pure silicilic acid modifications characterize the bond.
Through product-specific and format-specific high temperature firing, the corundum bricks have a high temperature-resistant mullite bond, a mullite-corundum bond or a pure corundum bond.
The application temperatures reach 1700°C for the mullite bond and up to 1800°C for corundum bond bricks, such as AL-95. The range of applications of the bricks covers almost all industrial sectors where high temperature processes are used and in which increased resistance to aggressive slags and atmospheres, as well as lot hot pressure flow and good thermal shock resistance are required.
