Is Activated Alumina Harmful?


Apr 12, 2020 ,

Activated alumina, like most commercial desiccant material, is not harmful to people or the environment. Activated alumina is a porous solid made of aluminum oxide, or Al2O3. Though non-toxic, aluminum oxide is mildly irritating to skin and eyes with too much exposure. Please, do not eat. Fun Fact: The crystalline form of Al2O3 is attributed […]
