High alumina ceramic ball (catalyst support filler) is made of alumina powder with very low silicon content. Its high purity and high strength make it extremely resistant to high temperature. It can be used in reaction tower to avoid leached silica covering downstream equipment or forming dirt or toxic catalyst carrier. It is widely used in petroleum, chemical industry, chemical fertilizer, natural gas, environmental protection and other industries, as the catalyst support material and tower packing in the reactor. It has the characteristics of high temperature and pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acid, alkali and other organic solvents, and can withstand the temperature change in the production process. Its main function is to increase gas or liquid distribution point, support and protect the active catalyst with low strength.

High aluminum grinding ball, with high density, good mechanical strength and wear resistance, is an economic and widely used non-metallic grinding medium. This product is widely used in mechanical, electronic, aerospace and other fields.
