Details of our corundum brick
1.Corundum Brick contain more than 90% of aluminum oxide that have another name is alumina oxide bricks.
2.Corundum brick is manufactured using high quality synthetic electro-fused corundum and sintered corundum and finely grained highly alumina raw materials with ceramic and chemical bonding.
3.This brick is shipped under high pressure and fire with high temperature with scientifically and reasonably gradating and adding good performance of additives.
Feature of Our corundum brick
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,alkali corrosion resistance.
Applications of our corundum brick
Corundum Bricks are mainly used in the linings in decomposing furnaces for petroleum and chemical industry, as well as the chemical fertilizer industry. They are also used as high temperature kiln linings and furnitures in metallurgical industry.
