Description for Corundum Brick

Corundum brick enjoys popular like in the industry manufacturing. Corundum brick not only plays a good performance in fire-resistant, but also has strong resistant to erosion. Corundum bricks are refractory products with over 90% content of Al2O3 and its principal crystalline phase is corundum. The service temperature of Corundum Bricks reaches up to 1800°C. Corundum brick price is mainly subjected to its raw materials.

Classification of Corundum Brick

Classify corundum refractory into two types according to the content of Al2O3 from 90% to 99%:

High purity corundum products: with 98%~99% content of Al2O3.
Low purity corundum products: with 90%~98% content of Al2O3.

Classify corundum refractory into two types according to manufacturing process:

Sintered corundum brick
Fused corundum block
