Perforated ceramic ball is a new product developed on the basis of inert ceramic ball. It is perforated with the diameter axis of the sphere, which not only has certain mechanical strength, chemical stability, and thermal stability like inert ceramic ball, but also increases the specific surface area and porosity, thereby increasing the dispersion and flux of the material and reducing the system resistance. Since its launch on the market, perforated ceramic balls have been widely used in the petroleum, chemical, and natural gas industries to replace inert ceramic balls as covering and supporting fillers for catalysts.
