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, further more it has higher dispersion and flux of the fluids, more surface area and lower resistance resulting from the perforated hols on the ball body. As a new efficient support and covering material of catalyst. It has been widely used in petroleum chemical, fertilizer, natural gas and environmental protection industries since put into market.
