Inert aluminum ceramic packing ball is widely used in many fields, including petroleum, 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.
It has some characteristics such as high strength,high chemical stability,and thermal stability.It can endure the high temperrature,high pressure and prevent corrosion from acid,alkali or various organic.Chemical compostion for 17% alumina ceramic ball:
