Corundum Mullite Tile
The corundum products produced by our company adopt imported plate corundum and high purity electrofused corundum as the main raw materials, apply advanced ultra-micro powder adding technology, and are made after mixing, molding, drying and high temperature firing in shuttle kiln. The products are characterized by high refractoriness, good thermal shock stability, high temperature strength, excellent corrosion resistance, strong slag resistance, small coefficient of expansion, low creep, anti-scaling, etc. They are suitable for use in high temperature kilns under various atmospheric conditions, and are widely used in high temperature sintering of zirconia ceramics, fluorescent materials, electronic ceramics, magnetic materials, ceramic powders, and in the equipment of petrochemical industry's gasification furnaces, synthetic ammonia two-stage conversion furnaces, carbon black reactors, and high temperature kilns in the glass industry. The products' external dimensions, physical and chemical properties, and The external dimensions, physical and chemical indexes and service life of the products have reached or exceeded the level of similar products at home and abroad.
