Corundum bricks
MARSREF is a supplier of corundum bricks, which refer to refractory products with Al2O3 content more than 90% and corundum as the main crystal phase. According to the type, they can be divided into sintered corundum bricks, corundum mullite bricks, fused zirconium corundum bricks, zirconium corundum bricks, etc. All of them are used high-purity sintered alumina, sintered corundum, fused corundum and other raw materials. The products have good stability performance, they belong to advanced refractory materials in the refractory industry.
Corundum bricks are widely used in high-temperature industrial furnaces such as iron-making blast furnaces and hot air blast stoves, steel-making refining furnaces, sliding system, glass melting furnaces, hazardous waste treatment, and petrochemicals.
