6.9: Ceramic Processing of Alumina
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 …
How aluminium is produced
The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a white powder. The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer ...
