High-alumina ceramic chemical filling ball (catalyst support filler) is made of high-temperature calcined alumina powder. Its high purity and high strength can make it extremely resistant to high temperatures. It is widely used in petroleum, chemical, chemical fertilizer, natural gas and environmental protection industries, as the covering support material and tower packing of the catalyst in the reactor. It has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. So it can withstand the corrosion of acid, alkali and other organic solvents, and can withstand the temperature changes that occur during the production process. Its main function is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength.

The chemical filling ball has high temperature resistance and good strength. It is a high-alumina ceramic ball with extremely wide application.
