High Alumina Ceramic Ball

Ceramic Balls are widely used in many fields, including petrolerm chemical engineering, fertilizer production, natural gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers. with stable chemical features and a low rate of water absorption, they can resist high temperatures and high pressure. They can also resist the corrosion of acid, alkali and some other organic solvents, and are able to stand the change in temperature during the manufacturing process. The main role of these ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.
