Aluminium hydroxide gels can be dehydrated (e.g. using water-miscible non-aqueous solvents like ethanol) to form an amorphous aluminium hydroxide powder, which is readily soluble in acids. Heating converts it to activated aluminas, which are used as desiccants , adsorbent in gas purification, and catalyst supports .
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 m 2 /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 ...

The gel-like aluminum hydroxide Al(OH) 3, also called alumina trihydrate (ATH), is converted via a second reaction step (usually slowly over a few hours at room temperature, more rapidly in a few minutes at higher temperatures) into aluminum oxide, Al 2 O 3:
It's also a great choice if you're looking for an aluminium-free option. As one Amazon reviewer pointed out, "Most aluminum-free and natural deodorants are the stick, not gel. I found this when ...
Anodes made of pure aluminium are corroded by the electrolyte, so the aluminium is usually alloyed with tin or other elements. The hydrated alumina that is created by the cell reaction forms a gel-like substance at the anode and reduces the electricity output. This is an issue being addressed in the development work on Al–air cells.
Gel: Gel deodorants typically come in the same type of container as solid sticks, but have a thick, liquid consistency. Gels can be messier and take longer to dry, but generally go on clear ...
