was first produced commercially in 1855 in France
, by H. Sainte-Claire Deville. This was done by reducing Aluminium Chloride
. The French government
supported the technique financially, since Napoleon
the third considered it to be useful in body armour
. In the five years fater 1855, the price fell from $US500 to $US40, but the emperor
only received a few helmets, a dinner set and a few toys. Indeed, Aluminium
was more expernsive than gold
at the time.
In 1886, Hall and Heroult independently discovered a more economic method for the production of Aluminium. This is known as the Hall-Heroult Process. This allowed the price to drop to less than $US4 per Kg.
Alumina is extracted from Bauxite, using the Bayer Process. It is this Alumina which is made into Aluminium by the Hall-Heroult Process
