Introduction of mullite corundum brick:
Mullite corundum brick is adopted imported tabular corundum, high purity fused corundum as raw material, use advanced micro powder addition technique, after mixing, drying, shaping, sintering at high temperature furnace.
Application of mullite corundum brick:
Primarily used for lining of the shuttle kiln for calcining refractory material, industrial ceramics , domestic ceramics and the bricks for the high temperature zone of tunnel kiln, insulation brick for high-temperature furnace.
