Product Description

3/8" 99% high purity alumina ball ceramic

The Zhongci 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 Zhongci 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 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.

Inert ceramic (porcelain) balls are used to fill and support the catalyst layer in catalytic columns and reactors, and as grinding bodies in ball mills.
The balls are made of high quality solid pressed silicate porcelain with an aluminum oxide content of Al2O3 -92% (in the range of 92~99%). They have high mechanical strength, resistance to acid, alkali, and some organic solvent, and resistance to thermal shock, which makes them all ideal choice for support of all types of catalysts.
Ceramic Balls are available to the order of sizes from 3 mm to 50 mm in diameter. Other types of ceramic products can be made upon your request indicating the necessary technical data.
