This article is about aluminium(III) oxide, Al 2 O 3. For other uses, see Aluminium oxide (compounds) . Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide.
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 mÂ²/g.ctivated alumina, when used as a fluoride filter, can be regenerated by a solution of lye (sodium hydroxide; NaOH), sulphuric acid (H 2 SO 4), or alum (KAl(SO 4) 2). The fluoride uptake capacity (FUC) of activated alumina can be up to 5000 mg/kg. The FUC can be determined as follows:
