Product Description

99% High Purity Alumina Ceramic Balls

Description:
XINGFENG 99% High Alumina Support Media is in chemical composition 99+% 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.
The XINGFENG 99% High Alumina Support Media has very excellent thermal properties, with its high density high-temperature resistance 1550ºC, also it's a good choice for heat retention or equilibration media.
For its superior chemical resistance, it's suitable for applications in olefin processes, such as ethylene dryers, where there's the polymerization problem.
