99 High Alumina Ball/Alumina
Detailed Product Description
High Alumina Support Media Spheres are in chemical compostion 99%+alpha alumina and a maximum 0.2% SiO2. Because of its high alumina content and low silica, it is very excellent and ideal product for hihg temperature and steam applications, such as secondary reformer in ammonia processing, where teached silica will coat downstream equpment or foul the catalyst bed.
High Alumina Support Media sphere has very excellent thermal properties , with its high density high-temperature resistance 1550 degree Centigrade, also it is a good choice for heat retention or equilibration media.
