Fused Corundum Refractory Brick Description
Fused Corundum Refractory Brick is a high-performance refractory material made from fused alumina, or fused corundum, which is primarily composed of high-purity aluminum oxide (Al₂O₃). Fused corundum bricks are known for their high strength, hardness, resistance to high temperatures, and excellent resistance to chemical corrosion, especially in extreme environments. These bricks are produced by fusing alumina at very high temperatures (over 2,000°C) and then casting or molding it into brick form, resulting in a dense and durable structure.
