In this process, bauxite is dissolved in hot sodium hydroxide solution, and insolubilities are filtered off. On cooling, aluminium hydroxide precipitates. The aluminium hydroxide is further calcined to give alumina, which may be smelted in the Hall-Héroult process in order to produce aluminium. aluminium(3+) hydroxide Aluminium(III) hydroxide Aluminum hydroxide Aluminum hydroxide (Al(OH)3) Aluminum hydroxide (usp) Aluminum hydroxide hydrate Aluminum trihydroxide Aluminum(III) hydroxide Di-mu-hydroxytetrahydroxydialuminum Trihydroxidoaluminium Trihydroxyaluminum AlH3O3 78.0036 77.989757403 aluminium(3+) ion trihydroxide aluminium(3+) ion trihydroxide 21645-51-2 [OH-].[OH-].[OH-].[Al+3] InChI=1S/Al.3H2O/h;3*1H2/q+3;;;/p-3 WNROFYMDJYEPJX-UHFFFAOYSA-K belongs to the class of inorganic compounds known as post-transition metal hydroxides. These are inorganic compounds in which the largest oxoanion is hydroxide, and in which the heaviest atom not in an oxoanion is a post-transition metal.
