Activated alumina ball is a white sphere, insoluble in water and organic solvent, soluble in strong acidic and alkaline solutions, moisture adsorptive in air, not expanding and cracking after adsorbing water. Activated alumina ball has the characters of high strength, resistance to sulfate poisoning and good thermal stability. Activated alumina ball is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material.
