Specifications

1.big surface area and free volume
2.Heat-resistance
3.ISO9001:2000...
Application: Industrial Ceramic

Professional manufactor for inert ceramic ball , alumina ceramic ball, Refractory ball and all kinds of water treatment ceramic ball.

Perforated ceramic ball used as supporting or covering material.

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: furthmore 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 in petroleum chemical, fertilizer, natural gas and environmental protection industries since put into market.
