Description of product 
Inert alumina balls are widely used in petroleum, chemical engineering, fertilizer, smelting, and gas and environment protection. They are used as covering and supporting material of catalyst in reaction vessel and as packing in towers. Ceramic ball has the feature of high temperature and, 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. 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.

Advantage
1. Excellent stability 
2. High mechanical strength 
3. Resist high temperatures 
4. Resistance to thermal shock 
5. Resist the corrosion of acid, alkali and some other organic solvents.
