Performance features and uses:
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 supporting and covering material of catalyst, it has been widely used in petroleum chemical, fertilizer, natural gas and environmental protection industries since been put into market.
