 alumina ceramic balls Product Details

     Inert alumina ceramic ball is industrial alumina and kaolin as the main raw material, through forming and high temperature above 1300 ? sintering production. It has high mechanical strength, stability and thermal stability of chemistry features, it can be resistant to high temperature and high pressure and acid, alkali, salt, and various organic solvent corrosion, widely used in petroleum, chemical industry, fertilizer industry, natural gas and environmental protection and other industries. As support and cover material, catalyst in the reactor can buffer into the liquid and gas in the reactor on the impact of the catalyst, protect the catalyst, and improve the distribution of liquid and gas in the reactor.
