High alumina ceramic ball

1.High strength
2.High chemical stability
3.High thermal stability
High alumina ceramic ballare used as catalyst, absorbent, desiccant and drying agent in petroleum, chemical, fertilizer, natural gas and environmental protection industries. As a catalyst reactor coverage tower packing materials and support, the major role is to increase distribution of gas or liquid, support and protect the intensity of low strength activity catalyst.
