Inert Alumina Ball-99
Description:
It is 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.
