high alumina ceramic balls 3mm 6mm 10mm 19mm 38mm 50mm 92% Al2O3 support media alumina ball
92% High Alumina Ceramic Ball is in chemical composition92+% alpha alumina and a maximum 2wt% SiO2. Because of its high alumina content and low silica(SiO2), it's a very excellent and ideal product for high temperature and steam applications.
The Chemxin 92 High Alumina Support Media has superior chemical resistance and very excellent thermal properties, with its high density high-temperature resistance 1550℃, also it's a good choice for heat retention or equilibration media.
