Product Description

Alumina ball have the advantages of high strength, high stabilities to chemical and thermal circumstances. It can resist the corrosion to acid, alkali, salt and all organic solvents. Being used as a supporting and a covering materia of catalyst in reactors, oil refinery, chemical, fertilizer production, natural gas and environmental protection industries. The main role of these ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.
