High alumina ceramic balls (catalyst support filler) are made from aluminum oxide powder with very low silicon content. Its high purity and strength make it extremely resistant to high temperature and is used in the reaction tower to avoid the leaching of silica soil covering downstream equipment or forming dirt or toxic catalyst carrier. It is widely used in petroleum, chemical industry, chemical fertilizer, natural gas and environmental protection industries. It is used as covering and supporting material of catalyst in reactor and packing of tower. It has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. Can withstand the corrosion of acid, alkali and other organic solvents, and can withstand temperature changes during production. Its main role is to increase the gas or liquid distribution point, support and protect the strength of the active catalyst is not high.

● High aluminum grinding ball, with high density, mechanical strength, good wear resistance, is an economical, widely used non-metal grinding medium. The products are widely used in machinery, electronics, aerospace and other fields.
