What Is the Origin of the Name Aluminum? Officially discovered by Hans Christian Oersted in Denmark in 1825 and used by the ancient Greeks and Romans in early civilization, aluminum is a mineral found in the earth's crust. Aluminum is most often used in kitchen utensils, building decor and construction materials.
Aluminium was first isolated by Hans Christian Oersted in 1825 who reacted aluminium chloride (AlCl 3) with potassium amalgam (an alloy of potassium and mercury). Heating the resulting aluminium amalgam under reduced pressure caused the mercury to boil away leaving an impure sample of aluminium metal.
