Ceramic balls are resistant to acid, alkali, salt and all organic solvents.
Ceramic balls are used as support and covering material in reactors in oil refinery, chemical, fertilizer, natural gas and environmental protection industries
Ceramic balls can improve the distribution of gas & liquid and protect the catalyst from shocking by the rushing fluids
