99% ceramic alumina balls as support media

Description:

99% alumina ballsis called pure alumina ball. Equaled Denstone®99 Support Media.It is in chemical composition99+% 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.It has a high purity, excellent thermal propertoes.high temperature, high pressure resistance. And low water adsorption.
