Glass Furnace Pressing Corundum Refractory Brick High Purity
The Description:
Corundum brick with alumina as the main raw material, the main crystalline phase of corundum shaped refractory products called corundum brick. Corundum brick has excellent corrosion resistance, wear resistance, high temperature strength, load softening temperature, creep and other thermodynamic properties. Corundum brick has high volume density and good thermodynamic properties, which makes corundum brick resistant to thermal, chemical and structural damage caused by gasifier and other industrial furnace operation.

Product feature:
Corundum brick can be divided into sintered corundum brick and fused corundum brick two kinds. Sintered corundum bricks can be made by sintering method by using sintered alumina and fused corundum as raw materials or alumina/silica clinker with high alumina/alumina ratio and sintered alumina. The product has high strength, high stability, corrosion resistance and thermal shock resistance and other excellent characteristics, widely used in high temperature and high pressure process equipment, such as refractory brick, refractory mud and other fields.
