Alumina ball used as chemical processing industry as catalyst bed support, with extremely high crushing strength
(1)Product overview
Inert Alumina Ceramic Ball have the advantages of high strength, high stabilities to chemical and thermal circumstances. It can resistant to acid, alkali,salt and all organic solvents. Being used as a support and a covering material in reactors in oil refinery, chemical, fertilizer, natural gas and environmental protection industries, it can improve the distribution of gas& liguid and protect the catalyst from shocking by the rushing fluids.
