Corundum mullite brig is a high alumina refractory made of corundum and mullite. Corundum - mullite brick refers to refractory products made from high purity or relatively pure raw materials. The presence of low melting point oxide impurities will reduce its high temperature performance. The pure mullite raw materials, especially the alkali metal oxide content should be as low as possible, are synthesized from industrial alumina powder and pure clay, bauxite or silica. The products made with mullite grain as aggregate have good thermal shock resistance but poor erosion resistance, and the products made with corundum sand as aggregate have good corrosion resistance but poor thermal shock resistance.



It has good high temperature strength, high temperature creep resistance, thermal shock resistance and erosion resistance. A kind of typical corundum - mullite brick is: the physical and chemical properties of Al2O3 > 85%, Fe2O3 0.45%, show porosity 19%, room temperature compressive strength is greater than 55 mpa refractoriness under load is greater than 1700 ℃, plus hotline change (1600 ℃, 3 h) - 0.1%, thermal shock resistance (1100 ℃ water) greater than 30 times. ?
