| Introduction:
Fire Resistance ceramic ball can be divided into ordinary ceramic ball and high alumina ceramic ball.The ordinary ceramic ball is suitable for the translater and converter in sulphuric acid and fertilizer industries.And the high alumina one fit for hot air furnace,heating & converting furnace and other devices in used and steel industries
Fire resistance ceramic ball are 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,and can stand the change in temperature during the application.Ceramic balls can increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.
