(1) Product Description
Perforated ceramic ball is developed on the basis of inert ceramic ball .It has an adequate mechanical strength, chemical and thermal stability as the normal inert one; furthermore it has higher dispersion and flux of the fluids, more surface area and lower resistance resulting from the perforated holes on the ball body. As a new efficient support and covering material of catalyst. it has been widely used in oil refinery, chemical, fertilizer, natural gas and environmental protection industries since put into market.
