Product Description

Corundum Brick that have another name is alumina oxide bricks. it is made mainly of calcined alumina, mullite, corundum . and contain more than 90% alumina content.
Corundum brick is manufactured using high quality synthetic electro-fused corundum and sintered corundum and finely grained highly alumina raw materials with ceramic and chemical bonding. This brick is shipped under high pressure and fire with high temperature with scientifically and reasonably gradating and adding good performance of additives.
