Activated alumina is a highly porous form of aluminum oxide (Al₂O₃) widely used as an adsorbent, desiccant, water-treatment media, and catalyst support. Unlike dense aluminum oxide used primarily for ceramics, abrasives, and refractory materials, activated alumina is engineered to have a large internal surface area and a network of microscopic pores. These characteristics give it a strong ability to adsorb water, fluoride, arsenic, and other polar contaminants.
