alumina ceramic ball
1.Performance characteristicsInert Ceramic Balls are with the advantages such as high strength, high chemical stability and thermal stability, it can resistant to high temperature, high pressure and acid, alkali, salt and various organic solvents.Being used as a support and a covering material in reactors in petroleum, chemical, fertilizer,natural gas and environmental protection industries, it can protect the catalyst from shocking by the rushing fluids,and improve the distribution of the gas and liquid.
