Aluminum oxides and hydroxides. The many forms of aluminum oxides and hydroxides are linked by complex structural relationships. Bauxite has the formula Al x (OH) 3-2x (0 < x < 1) and is thus a mixture of Al 2 O 3 (α-alumina), Al(OH) 3 (gibbsite), and AlO(OH) (boehmite). The latter is an industrially important compound which is used in the form of a gel as a pre-ceramic in the …
