Inert Ceramic Balls As Support Media In Tower Packing - China

Inert alumina ball-17 is called ceramic ball 17%~19% Al2O3 - It is equal to Denstone® 57 Support Media.

They are the most widely used support media in the world.

It is made of 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.
