Product Description

 

Product Description

      Ceramic balls are widely used as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas, for examples, petroleum, chemical industry, chemical fertilizer, natural gas and environmental protection etc. The ceramic balls have the advantages of high temperature and high pressure resistance, low water adsorption, stable chemical performance, it also resistance to acid, alkali, and some organic solvent.

Advantage
 

1. High hardness and high precision. Our silicon nitride ceramic balls have a hardness of 90-95 and a processing accuracy of G10.
2. Good stability and resistance to strong acids and alkalis.
3. High wear resistance. Low wear (ppm level), minimizing equipment wear.
4. High temperature resistance. The working temperature of the ceramic balls produced by our company can reach 1300 degrees Celsius or even higher
5. Light weight. Low density, the weight is only 50%-60% of ordinary steel ball.
