Our corundum products adopt imported plate corundum and high purity electric melting corundum as main raw materials, apply advanced ultramicro power adding technology and go through the process of mixing, molding, drying and burning in high temperature shuttle type kiln. Featuring high fire resistance, good thermal shock stability, large high temperature strength, high slag resistance, small expansion coefficient, low creep property and stripping resistance, it is suitable for high temperature kilns under any conditions and expansively applied for zirconia ceramics, fluorescent material, electronic ceramics, magnetic material and ceramic power high temperature sintering in gasification furnaces, synthesis ammonia secondary conversion furnaces, carbon black reaction furnaces in petrochemical industry and high temperature kilns in glass industry. The overall dimensions, physiochemical indexes and service life of the product have reached or exceeded the level of similar products at home and abroad.
