Product Description
Zhongci Ceramic Bearing Alumina Porous Ceramic Ball for Chemical Filling
Porous ceramic ball introduction :
Have inert ceramic ball's advantage and improve the surface area and stability. It is a new developed product in our company, and we focus on the centre of the ball to open holes, it has high stability and flexibility. And improves the void of the specific surface area, lowing the resistance of the system. So it can be widely used in oiling, chemical, industries.and support or protect the active catalyst , which especially have the comparatively lower mechanical strength.
