           Inert Ceramic Ball                           High Alumina Ball                    Alumina Grinding Ball

 

High density 1 inch alumina al2o3 ceramic ball for petrochemical

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.
