In 1779 Peter Woulfe
deduced the existence of a new element - Tungsten - from his analysis of the
mineral wolframite (an iron manganese tungstate mineral).
Tungsten
was isolated as tungstic oxide (WO3) in 1781 by Carl W. Scheele from the
mineral scheelite (calcium tungstate). However he did not have a suitable
furnace to reduce the oxide to the metal.
Tungsten
was finally isolated by Fausto and Juan Jose de Elhuyar in 1783 by reduction
acidified wolframite with charcoal.
The
element name comes from the Swedish words 'tungsten', meaning heavy stone.
The
chemical symbol, W, comes from the original name of the element, Wolfram.
