PRODUCTS DESCRIPTION

Inert Porcelain Ceramic Balls Introduction:


The High Alumina Support Media is equal to 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, such as secondary reformers in ammonia processing, where leached silica will coat downstream equipment or foul the catalyst bed.


High Alumina Ceramic Balls has very excellent thermal properties, with its high density high-temperature resistance 1550℃, also it's a good choice for heat retention or deceleration media.


For its superior chemical resistance, it's suitable for applications in ole fin processes, such as ethylene dryers, where there's the polymerization problem.
