The inert perforated ceramic balls have not only certain mechanical strength, chemical and thermal stability, but also improve specific surface areas and void volume, so the dispersing property and the flux of materials are increased, system resistance is reduced too. It can be broadly applied to petroleum, chemical and natural gas industry, etc.
