Inert Ceramic Ball

Detailed Product Description


Porous ceramic balls are widely used support media in the world because of their excellent consistence and reliability. Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strengthand resistance to thermal shock. This makes them all ideal choice for support of all types of catalyst.
