Activated Alumina

Activated Alumina Overview

From Wikipedia, the free encyclopedia

Activated Alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 m²/g. The compound is used as a desiccant (to keep things dry by adsorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water. It is made of aluminium oxide (alumina; Al2O3). It has a very high surface-area-to-weight ratio, due to the many “tunnel like” pores that it has. Activated alumina in its phase composition can be represented only by metastable forms (gamma- Al₂O₃ etc.). Corundum (alpha- Al₂O₃), the only stable form of aluminum oxide, does not have such a chemically active surface and is not used as a sorbent.
