Inert balls with a medium aluminum oxide content of 25 mm

Inert balls with an average content of aluminum oxide are widely used in many industries, including petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. They are used as coatings and auxiliary materials of catalysts in reaction vessels and as a bulk packing in columns. They have stable chemical properties and low water absorption rate, resistant to high temperatures and high pressure, as well as to corrosion by acid, alkali and some other organic solvents. They withstand temperature changes during the production process. The main role of inert ceramic beads is to increase the distribution spots of gas or liquid, as well as to maintain and protect the activating catalyst with low strength.
