          1. ceramic balls (Al2O3: 90~99%)



            Inert ceramic balls 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.
