Detail Description

1. Product Description
Inert alumina ceramic ball has 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 environment protection industries, Inert alumina ceramic ball can improve the distribution of gas and liquid, protect the catalyst from shocking by the rushing fluids.
