High Alumina Ceramic Balls
HQ-Al2O3 99% high alumina ball is made from industrial alumina and processed by shaping and firing, which has two types according with main application, one is Chemical industry corundum ceramic balls (TYPE A), and the other is thermal storage corundum ceramic balls (TYPE B).It widely used as catalyst bed support media in refining, petrochemical and gas applications, where low silica content or high alumina is required. With characteristics of high hardness, high density, high crush strength, excellent thermal properties, etc.
