SARMAD SHAMIM Corundum Bricks
Corundum bricks of ≥ 90 % Al₂O₃ are manufactured using synthetic fused corundum and sintered corundum and finely grained highly aluminous raw materials with ceramic and chemical bonding. Corundum brick is build up for the furnace that have to stand on high temperature especially more than 1550℃ and resistance to chemical corrosion.
It is widely used in lining of ovens of petrochemical industry,Burner block,Bridge brick,the car top block and the other parts which need to stand in high temperature or high refractoriness under load.
