Activated alumina

Activated aluminum oxides are highly porous, granular desiccants with a large internal surface area. Their fine pore structure binds water vapor and other polar substances. Activated aluminum oxides are chemically stable, resistant to numerous solvents, regenerable, and insoluble in water.
