6.9: Ceramic Processing of Alumina Chemistry

2020-9-8  Today, alumina is prepared by the Bayer process, in which the mineral bauxite (named for Les Baux, France, where it was first discovered) is dissolved with aqueous hydroxides, and the solution is filtered and treated with CO 2 to precipitate alumina. With availability of both the mineral and cheap electric power being the major considerations in the economical production of aluminum, it is not

Aluminum processing Ores Britannica

Aluminum processing Aluminum processing Ores: Aluminum is the third most abundant element on Earth’s surface. Only oxygen and silicon are more common. Earth’s crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.

6.9: Ceramic Processing of Alumina Chemistry

2020-9-8  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 production of
