Corundum Brick Description

Corundum brick is a refractory material with alumina (Al2O3) as the main component, with a content of more than 90%. Due to its high melting point, high hardness and high strength, it is widely used in high-temperature kiln linings and kiln furniture.

Feature

（1）High temperature resistance

（2）High strength,high compression resistance

（3）Excellent thermal shock resistance

（4）High bulk density, good thermal conductivity

（5）Good wear resistance and acid

（6）alkali corrosion resistance

Production process

Sintering method: Use sintered alumina and phosphoric acid or other binders to make unburned corundum bricks.
Electrofusion method: High-purity alumina raw materials are melted and cast at a high temperature of more than 2000°C.
