Aluminium

What the name means: The name comes from the Latin word alum. In 1761 Guyton de Morveau gave the name "alumine" to the part of alum associated with a metal. Humphry Davy, in 1807, called the metal base "alumium". Davy later agreed to a change in the name to aluminium (although North Americans refer to the metal as aluminum).

Who identified aluminium?: Although the presence of a metal base has been known by both Morveau and Davy, the metal was first isolated by Hans Christian Øersted in 1825. Øersted extracted the metal from aluminium chloride.

About aluminium: Aluminium is silvery and very light for a metal. It is soft and not very strong but it can be mixed with other metals to form alloys that are stronger. Aluminium is a very useful metal. Because it is a light metal it is used for making airplanes. It conducts electricity, so alloys of aluminium are useful in electric wiring. It conducts heat very well so it is used to make cooking pans. Aluminium metal is reactive so it is not found naturally as the element. It is extracted from bauxite (aluminium oxide) for industrial use.
