23~30% Al2O3 Inert Ceramic Balls As Catayst Support/Covering

The ceramic balls are manufactured very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, which are broadly utilized as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas, for example, petroleum, chemical industry, chemical fertilizer, natural gas and environmental protection etc. Upon request, we the optimum packing for the particular problem or application as well as the optimum material and size.
