Activated alumina balls are highly porous, thermally stable forms of aluminum oxide (Al₂O₃) with a large specific surface area . They serve as desiccants, adsorbents, and catalyst carriers in various industrial applications, including gas drying, air separation, water purification, fluoride removal, and hydrogen peroxide production. Their performance relies on selective adsorption via surface hydroxyl groups and pore structure, and they can be regenerated by heating, making them cost-effective and reusable
