Activated Alumina CAS No. 1344-28-1 for a Wide Range of Adsorbent and Catalyst Applications

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 absorbing 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.

Application:
Activated alumina is used for a wide range of adsorbent and catalyst applications including the adsorption of catalysts in polyethylene production and hydrogen peroxide production, as a selective adsorbent for many chemicals including arsenic, fluoride, sulfur removal from fluid streams (Claus Catalyst process).
