alumina ball 1/8" have the advantages of high strength, high stabilities to chemical and thermal circumstances. It can be 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 & liquid and protect the catalyst from shocking by the rushing fluids.
