  HQ-DA Inert Ceramic Balls

  (1)Product Description
  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 support and a covering material in reactors in oil refinery, chemical, fertilizer, natural gas and environmental protection industries, it can improve the distribution of gas & liquid and protect the catalyst from shocking by the rushing fluids.
