Medical Definition of ALUMINA. : an oxide of aluminum Al2O3 that occurs native as corundum and in hydrated forms (as in bauxite) and is used in antacidsâcalled also aluminum 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:
