Refractory ceramic balls are mainly made of industrial alumina and refractory kaolin, processed by mixing, shaping and firing. Its high in mechanical strength and long life cycle, excellent chemical stability, and never reacts with the feeding material, excellent resistance to high temperature up to 1900 ℃. It is widely used as support and covering pickings for catalyst in shift converters, reformers, hydro converters, desulfurizers, and methanators, and can also be used as pickings in hot blast
