Feuerfeste Keramik-Kugel

Refractory Ceramic ballare broadly utilized as covering and supporting mterials of catalysts in reaction vessels and as packing in towers.They are widely used in petrolem chemical ,fertilizer ,natural gas and environmental protection industry. With stable chemical features and a low rate of water absorption,they can resist high temperatures and high pressure,and also can resist the corrosion of acid,alkali and some other organic solvents,andcan stand the change in temperature during the application.Ceramic ballscan increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.
