High Alumina Mullite Corundum fire brick white color 80%Al2O3 for Industrial furnaces
Mullite Corundum Fire 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 Fire 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 Fire brick features:
High temperature resistance
Good erosion resistance
Good chemical stability.
Mullite Corundum Fire brick has been used in blast furnaces, Iron furnaces, carbon black reactors and other high-temperature kilns.
