Perforated Ceramic Balls (KK Perforated Ceramic Balls) are designed to increase the specific surface area by perforating the inert ceramic balls along the diameter axis. In addition to the high mechanical strength, chemical stability, and thermal stability of inert ceramic balls, they also offer increased specific surface area and porosity, thereby enhancing material dispersion and flux while reducing system resistance. Perforated ceramic balls are widely used in industries such as petroleum, chemical, and natural gas as a covering support filler for catalysts, replacing inert alumina ceramic balls.
