1. Product Description
High alumina ball have extremlyhigh 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, it can improve the distribution of gas and liquid; protect the catalyst from shocking by the rushing fluids.
99% alumina ball is used for catalsyt supporting, heat exchange, and heat storage.
2. Chemical Composition
