Porous ceramic ball is a new product developed on the basis of inert alumina porcelain ball.it takes the ball diameter as the axis for opening holes,which has a certain mechanical strength,chemical stability and thermal stability,and increases the specific surface area and voidage, thereby increasing the dispersion and flux of the material and reducing the resistance of the system.
Application
Porous ceramic ball can be widely used in petroleum,chemical industries to replace inert alumina ceramic balls as catalyst covering supporting fillers.it can be widely used in petroleum, chemical and industries to replace inert alumina ceramic balls as catalyst covering supporting fillers.

Detailed Photos
The design principle of open porcelain ball includes the use of corundum and mullite as the main crystal phase,combined with feldspar glass and kaolin sintered body as the structural bridge,using the excellent properties of alumina sintered body,such as high mechanical strength,high temperature resistance,cold and hot resistance,oxidation resistance,wear resistance,very low chemical activity and strong acid and alkali corrosion resistance.
