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.
