aluminium (US aluminum) chemguide

Formation of pure aluminium oxide. Aluminium oxide (sometimes known as alumina) is made by heating the aluminium hydroxide to a temperature of about 1100 1200°C. Conversion of the aluminium oxide into aluminium by electrolysis. The aluminium oxide is electrolysed in solution in molten cryolite, Na 3 AlF 6. Cryolite is another aluminium ore, but is rare and expensive, and most is now made chemically.

Aluminium Element information, properties and uses

In this process aluminium oxide is dissolved in molten cryolite and then electrolytically reduced to pure aluminium. Making aluminium is very energy intensive. 5% of the electricity generated in the USA is used in aluminium production. However, once it has been made it does not readily corrode and can be easily recycled. Help text not available for this section currently History. Elements
