ICB-20 Inert Ceramic Balls
Inert Ceramic Balls 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 catalyst bed support and a covering material in oil refinery, chemical, fertilizer, natural gas and environmental protection industries, it can improve the distribution of gas & liquid, support and protect the activating catalyst from shocking by the rushing fluids.
Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.
