Porous Alumina Ceramic Ball as Support Media for Catalyst Media

Porous ceramic balls

Inert ceramic ballsupport Mediaare the mostwidely used support mediain 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 strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.
