Product Description

Inert Ceramic Ball High Alumina Ball Alumina Grinding Ball

1-1/2 inch 99% white high alumina ball for ethylene dryers

The XINTAO 99 High Alumina Support Media 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.

The XINTAO 99 High Alumina Support Media 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.
