Alumina ceramic ball is widely used in petroleum, chemical industry, chemical fertilizer, natural gas and environmental protection and other industries, as the catalyst in the reactor cover support material and tower filler. Alumina porcelain ball 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 inorganic solvents, and can withstand temperature changes in the production process. The main role of alumina porcelain ball is to increase the distribution point of gas or liquid, support and protect the active catalyst with low strength.

Alumina porcelain ball according to alumina content can be divided into ordinary porcelain ball, aluminum porcelain ball and high aluminum porcelain ball.

Alumina porcelain ball can be divided into inert alumina porcelain ball, active porcelain ball and refractory porcelain ball according to the nature of use.
