Corundum Brick Description
Corundum brick is a refractory material with alumina (Al2O3) as the main component, with a content of more than 90%. Debido a su alto punto de fusión, 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,alta resistencia a la compresión
（3）Excellent thermal shock resistance
（4）High bulk density, buena conductividad térmica
（5）Good wear resistance and acid
（6）alkali corrosion resistance

Proceso de producción
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.
