History

Torbern Bergman obtained from scheelite an oxide of a new element in 1781. In 1783, José and Fausto Elhuyar found an acid made from wolframite that was identical to tungstic acid. Later that year, in Spain, the brothers succeeded in isolating tungsten by reduction of this acid with charcoal, and they are credited with the discovery of the element. From Swedish, tung sten meaning heavy stone

DiscoverersFausto and Juan José de Elhuyar
Discovery LocationSpain
Discovery Year1783
Etymology (Name Origin)Swedish: tung sten (heavy stone): symbol from its German name wolfram.
PronunciationTUNG-sten (English)
Tungsten is considered to be of low toxicity
The chemical symbol, W, comes from the original name of the element, Wolfram

Uses

Tungsten and its alloys are widely used for filaments in electric bulbs and electronic tubes. Tungsten carbide is of great importance to the metal-working, mining, and petroleum industries. Tungsten oxides are used in ceramic glazes and calcium/magnesium tungstates are used widely in fluorescent lighting. Made into filaments for vacuum tubes and electric lights. Also as contact points in cars. Combined with calcium or magnesium it makes phosphors. Tungsten carbide is extremely hard and is used for making cutting tools and abrasives.

Sources

Occurs in the minerals scheelite (CaWO4) and wolframite [(Fe,Mn)WO4].
