Inert Ceramic Ball are widely utilized as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas as petroleum, chemical industry, chemical fertilizer, natural gas and support or protect the active catalyst, which especially have the comparatively lower mechanical strength.

Introduction
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.
