Product Show
--- **Product Description** Inert Alumina Ceramic Balls are widely used in the petrochemical, chemical, fertilizer, natural gas, and environmental protection industries. They serve as covering and supporting materials for catalysts in reactors and as packing in towers. Their main function is to enhance the distribution of liquids and gases, while protecting and holding the activated catalysts that have low strength. --- **Technical Data**
