Customized shaped Corundum Mullite firebrick Kiln Refractory material 85%Al2O3
Corundum Mullite Firebrick is mainly composed of corundum and mullite, Al2O3 content is 72~90%, and the main crystal phase is the shaped refractory products of mullite and corundum. It is fired at high temperature in an oxidizing atmosphere by adding suitable alumina, superfine silica powder and additives. The high temperature stable crystal phase is mullite and corundum.
Corundum Mullite Firebrick is a kind of high-grade refractory material that not only has the high temperature performance of corundum material, but also integrates the good thermal shock resistance of mullite. Such as high strength, high volume density, good erosion resistance, good chemical stability and high temperature resistance. The product has been used in blast furnaces, Iron furnaces, carbon black reactors and other high-temperature kilns.
