Introduction:
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.
