  • Description
  • Specification

99 Alumina Ball

99% pure alumina Ceramic Ball, is equal 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. 

Xintao 99% pure alumina Ceramic Ball, has very excellent thermal properties, with its high density, 

high-temperature resistance 1550℃, also it's a good choice for heat retention or equilibration media. 

Typical Application:

a) 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.

b) It's suitable for applications in olefin processes, such as ethylene dryers, where there's the polymerization problem.

Warranty:

By National Standard HG/T 3683.1-2014 .

Free consultation during the warranty period.
