Product Details

99% Alumina Ceramic Ball

Product Description.

The Chemxin 99 High Alumina Support Media is in chemical composition 99+% alpha alumina and a maximum 0.2wt% 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, such as secondary reformers in ammonia processing, where leached silica will coat downstream equipment or foul the catalyst bed.
