corundum-mullite series refractory materials


¡¡¡¡The corundum-mullite series refractory materials are the creative result owing to the unremitting efforts jointly made by our company and the 10-plus of postgraduates of different school years of the Structural Ceramics Research Institute, Xian Construction Science & Technology University. Such series products' properties have approached the advanced world level. With obvious use effect, the products are widely used for making push board, trencher and various ceramic containers. Due to the excellent features of heat-shocking resistance and no pollution to ceramic products, so they are also widely used as lining of aluminum refining furnace, corrosion-resisting and permeation-preventing.
