Alluminium
Aluminium was first extracted in 1827 from aluminium chloride by treating it with sodium :
AlCl3 + 3Na → Al + 3NaCl
But the process was very expensive. Impressed by its properties, metallurgists all over the world attempted to develop a process for the commercial production of aluminium. But it remained a costly metal till 1886, when Heroult in France and Hall in USA succeeded in developing independently a process for the extraction of aluminium. Thus began large-scale production of aluminium in several parts of the world. Hall-Heroult process came into extensive use towards the end of the nineteenth century.
