corundum-mullite series refractory materials


The corundum-mullite series refractorymaterials are the creative result owing to the unremittingefforts jointly made by our company and the 10-plusof postgraduates of different school years of theStructural Ceramics Research Institute, Xian ConstructionScience & Technology University. Such seriesproducts' properties have approached the advancedworld level. With obvious use effect, the productsare widely used for making push board, trencherand various ceramic containers. Due to the excellentfeatures of heat-shocking resistance and no pollutionto ceramic products, so they are also widely usedas lining of aluminum refining furnace, corrosion-resistingand permeation-preventing.
