Corundum Ceramic Ball Suppliers, Corundum Ceramic Ball Manufacturers.
Inert Ceramic Balls' main role is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.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 as well as some other organic solvents, and they are able to stand the change in temperature during the manufacturing process.
