Inert alumina ceramic balls are manufactured from very high quality chemical-porcelain clay materials. According to the different content of Al2O3, the packing ceramic ball is divided into: common ceramic ball, inert ceramic ball, medium alumina ball, high alumina ball and 99% alumina Ball, actived alumina ceramic ball, opening hole ceramic ball, micro porous ceramic ball, heat storage ceramic ball.
