Molybdenum: applications

Molybdenum is mainly used as an alloying component in order to increase the strength as well as the corrosion- and heat resistance. Due to its high heat resistance it is used for the production of components in the aerospace sector. In form of foils it is used as gas-proof current lead for halogen lamps and high-pressure gas discharage lamps.


Molybdenum: history and occurrence

For a long time molybdenum was mistaken for galena or graphite. Only in 1782 Peter Jakob Hjelm managed to extract the element in a pure form. As it gets extremely brittle due to slight impurities of oxygen or nitrogen it was ignored for a long time. Only end of the 19th century employees of the French company Schneider & Co., a producer of armoured conduits, realised the applicability of molybdenum as an alloying component. For this reason there was a big demand for molybdenum during both world wars but it became less important again afterwards.

Molybdenum usually occurs as molybdenite but it can also be found in the minerals wulfenite and powellite. It is mainly extracted in form of molybdenite as a by-product in copper mining. Large reserves can be found in the United States, China, Chile, Canada and Peru. The global production amounted to 221.000 t in 2009 with the United States as the biggest producer.
