Advantage:

1.Excellent  and stable quality.

2.Plenty of stocks.

Material: alumina ceramic

Size Range: 1mm~150mm

Characteristics of alumina ball:

Alumina balls are in chemical composition 99+% 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.

99 High Alumina balls have very excellent thermal properties, with its high density high-temperature resistance 1750C, also it's a good choice for heat retention or equilibration media.
