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 results 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.
