Corundum Brick

Product advantages: high strength, high temperature resistance, corrosion resistance, and good chemical stability.

nkọwa ngwaahịa

High-purity corundum bricks use tabular corundum and fused corundum as the main raw materials, through scientific and reasonable grading, with excellent performance additives, high-pressure molding, high-temperature sintering, and the refractory products are characterized by high strength and high temperature resistance. Corrosion resistance and good chemical stability.
