85% Al2O3 White Mullite Corundum Refractory brick for Industrial kilns High strengh
Mullite Corundum Refractory brick is mainly composed of corundum and mullite, 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. Made. The alumina content is 72~90%, and the high temperature stable crystal phase is mullite and corundum.
Mullite Corundum Refractory brick is a kind of high-grade refractory material with high corrosion resistance. It not only has the high temperature performance of corundum material, but also integrates the good thermal shock resistance of mullite.
Mullite Corundum Refractory brick features:
High temperature resistance
Good erosion resistance
Good chemical stability.
Mullite Corundum Refractory brick has been used in blast furnaces, Iron furnaces, carbon black reactors and other high-temperature kilns.
