The alumina inert ball is characterized by high temperature resistance, high pressure resistance, low water absorption rate and chemical stability. The inert alumina ceramic ball is mainly used for increasing distribution of gas and liquid, and supporting catalysts whose activity are not too high.

An extensive application of inert ceramic ball is found in hydrocracking device, refining unit, catalytic reforming device, isomerization unit and demethylation device in petrochemical plants, chemical fiber plants, alkyl benzene plants, aromatic plants, ethylene plants and natural gas plants.
