Timeline of tungsten
This is a timeline of tungsten, attempting to describe historic events related to the discovery, science and industrial development of the metal.
|Time period||Development summary|
|16th century||Tungsten is first discovered in the 16th century in Saxony by tin miners, who find and then recognize the metal as a newly useful and undiscovered asset.|
|18th century||Chemists begin identifying the elements that make up mater. In this century tungsten is first isolated.|
|20th century||In the 1930s, new applications arise for tungsten compounds in the oil industry for the hydrotreating of crude oils. In the 1940s, during World War II, the Germans are the first to use tungsten carbide core in high velocity armor piercing projectiles. In the 1950s, tungsten is added into superalloys to improve performance. In the 1960s, new catalysts are born containing tungsten compounds to treat exhaust gases in the oil industry.|
|21st century||Currently, most tungsten resources are found in China, South Korea, Bolivia, Great Britain, Russia and Portugal, as well as in California and Colorado. About 80% of world’s supply is controlled by China. Today, tungsten carbide is extremely widespread, with applications including metal cutting, machining of wood, plastics, composites, soft ceramics, chipless forming, mining, construction, rock drilling, structural parts, wear parts, and military components. Tungsten-steel alloys are used in the production of rocket engine nozzles, and superalloys containing tungsten are used in turbine blades and wear-resistant parts and coatings.|
|1556||Discovery||German mineralogist Georgius Agricola notes a material he calls lupi spuma ("wolf's foam"), which in German is wolf rahm. The mineral ore is today known as wolframite and is one of the main sources of tungsten. This explains the symbol "W" for the element.||Germany|
|1750||Discovery||Tungsten ore (now called scheelite) is discovered in the Bispberg´s iron mine in the Swedish province Dalecarlia.||Sweden|
|1757||Scientific development||Swedish chemist Axel Fredrik Cronstedt describes a light heavy mineral. He names it “tung sten” in Swedish, meaning “heavy stone”.||Sweden|
|1779||Scientific development||Irish chemist Peter Woulfe examines a mineral from Sweden and realizes it contains a new type of metal.|
|1781||Scientific development||German chemist Carl Wilhelm Scheele continues the research on the new metal and isolates an acidic white oxide. Scheele is the first to produce tungsten acid from tungsten ore.||Sweden|
|1781||Scientific development||The name "tungsten" is suggested by chemist Tobern Bergman.||Sweden|
|1783||Scientific development||Tungsten is first isolated by Spanish brothers Fausto Elhuyar and Juan José Elhuyar. They isolate the metal oxide from wolframite and reduce it to tungsten metal by heating it with carbon. The brothers call the new metal wolfram.||Spain|
|1820||Scientific development||One of the two economically important minerals of tungsten is named “wolframite” by German mineralogist August Breithaupt.|
|1821||Scientific development||German mineralogist Karl Cäsar von Leonhard proposes the name “Scheelite” for the mineral CaWO4, in honour of Carl Wilhelm Scheele.|
|1847||Technology||British Engineer Robert Oxland is granted a patent to prepare, form, and reduce tungsten to its metallic format.||United Kingdom|
|1847||Application||Tungsten salts are used to make colored cotton and to make clothes used for theatrical and other purposes fireproof.|
|1855||Application||Austrian chemist Franz Koller develops a tungsten steel.||Austria|
|1857||Technology||Robert Oxland patents his process for producing tungsten steel.||United Kingdom|
|1858||Application||Steels containing tungsten begin to be produced.|
|1868||Application||Mushet starts to manufacture high-carbon-vanadium-manganese-tungsten steels in England.||United Kingdom|
|1895||Scientific development||American inventor Thomas Edison finds that calcium tungstate is the substance with the best ability to fluoresce when exposed to X-rays.||United States|
|1900||Application||A special mix of steel and tungsten is exhibited at the World Exhibition in Paris.||France|
|1904||Application||Several European inventors almost simultaneously develop lamp filaments made with the metal tungsten. The first light bulbs using tungsten are patented in the year.|
|1908||Application||American physicist William D. Coolidge discovers that tungsten is an ideal filament material. Coolidge invents a process for making tungsten filaments which (combined with other improvements) produce lamps two and a half times as efficient as those used before.||United States|
|1909||Technology||Team led William D. Coolidge working at General Electric discover a process that creates ductile tungsten filaments through suitable heat treatment and mechanical working.||United States|
|1911||Application||The Coolidge process is commercialized. In a short time, tungsten light bulbs would spread all over the world equipped with ductile tungsten wires.||United States|
|1922||Policy||Tungsten is placed on the first official Government list of strategic minerals in the United States.||United States|
|1923||Application||A German electrical bulb company submits a patent for tungsten carbide, or hardmetal. The carbide is made by "cementing" very hard tungsten monocarbide (WC) grains in a binder matrix of tough cobalt metal by liquid phase sintering. The resulting material combines high strenght, toughness and high hardness.||Germany|
|1927||Application||The Krupp Laboratory at Essen, Germany, discovers that a serviceable product could be produced when the normally brittle tungsten carbide is mixed with a cemented material.||Germany|
|1940 – 1945||Application||Tungsten becomes a strategic metal during World War II as its resistance to high temperatures and its strengthening of alloys make it an important raw material for the arms industry.|
|1944||Book||K C Li, founder of Wah Chang Corporation in the United States, publishes a picture in the Engineering & Mining Journal entitled: “40 Years Growth of the Tungsten Tree (1904 – 1944)” which illustrates the fast development of the various tungsten applications in the field of metallurgy and chemistry.||United States|
|1977||Production||China is the biggest and most important tungsten ore concentrate supplier.||China|
|1979||Event||The first International Tungsten Symposium is held in Stockholm.||Sweden|
|1993||Financial||The price of tungsten reaches historical minimum, as a result of the collapse of the communist world together with a sudden fall in the worldwide tungsten consumption.|
|1995||Production||Two countries, China (69%), and the former Soviet Union (19%), account for over 80 percent of the world's production of tungsten.||China, Ex-USSR|
|2003||Application||Ammonium paratungstate, ferrotungsten, tungsten carbonate, and tungsten oxide are major exported products from China.||China|
|2009||Application||Tungsten filament bulbs start being phased out in the European Union.|
