| Description: | Inert Alumina Ball-17 Deion: 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.
