China Inert Alumina Ceramic Ball

1.Inert Alumina Ceramic Ball
2.high temperature and pressure resistance
3.low water absorption
4.stable chemical performance

Inert Alumina Ceramic Ball is widely used in many fields, such as petroleum, chemical engineering, fertilizer, smelting, medical treatment and environmental protection. They are used as covering and supporting material of catalyst in reaction vessel and as packing in towers. The main role of inert ceramic ball is to increase the distributing spot of gas or liquid,also support and protect the activated catalyst with low strength.

 

Our ceramic ball has the feature of high temperature and pressure resistance, low water absorption, and stable chemical performance. It can not only resist the corrosion from the acid, alkali and other organic solvent, but also the temperature change in production process.
