Introduction:
The XINTAO 65% Porcelain ceramic ball is in chemical composition70+% 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 XINTAO65 Alumina Support Media has very excellent thermal properties, with its high density high-temperature resistance 1450℃, 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.
Typical Application:
a) high temperature and steam
b)has very excellent thermal properties, with its high density high-temperature resistance 1450, c)it's suitable for applications in olefin processes, such as ethylene dryers
