Inert alumina ceramic balls are widely used in petroleum, chemical, fertilizer, and environmental protection industries, as a support material for the catalyst in the reactor and tower packing. Inert alumina ceramic ball has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acids, bases and other organic solvents and can withstand the temperature changes that occur during production. The main function of the inert alumina ceramic ball is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength.
