Corundum brick is a refractory material with corundum (alumina, Al2O3 content exceeding 90%) as the main crystal phase. Its characteristics include extremely high cold pressing strength, high wear resistance, high refractoriness under heavy load (over 1700°C) and good chemical stability. The product has excellent corrosion resistance and can resist the erosion of acidic or alkaline slag, metal and molten glass. Corundum bricks can be divided into two types: sintered corundum bricks and fused corundum bricks. The raw materials can be sintered alumina or fused corundum, and can also be manufactured by sintering by combining alumina clinker with a high aluminum-silicon ratio with sintered alumina.
