Corundum Brick
Product Description:
Corundum brick is manufactured using synthetic fused corundum and sintered corundum and finely grained highly aluminous raw materials with ceramic and chemical bonding.
Feature:
Corundum brick has features like high thermal shock resistance, big bulk density, high strength and abrasion resistance, strong acid and alkali corrosion resistance.
Application:
Corundum brick is widely used in furnace kilns of metallurgy, chemical engineering, electric and glass industry.
