Hans Christian Ørsted was the first to separate the element aluminium in 1825, using a reduction of aluminium chloride with a potassium amalgam. Although Ørsted published his findings on the isolation of aluminium in the form of small particles, no other investigators successfully replicated his findings until 1936. Ørsted is now credited with discovering aluminium. Ørsted's findings on aluminium preparation were developed further by Wöhler, with Ørsted's permission. Wöhler modified Ørsted's methods, substituting potassium metal for potassium amalgam for the reduction of aluminium chloride. Using this improved method, Wöhler isolated aluminium powder in pure form on 22 October 1827. He showed that the aluminium powder could convert to solid balls of pure metallic aluminium in 1845. For this work, Wöhler is credited with the first isolation of aluminium in pure form.
