Molybdenum (Mo)
Recognized as a new element in 1778, the first impure form of molybdenum was produced in 1782.
The metal is silvery white and very hard, although softer and more ductile than tungsten. Used as an alloying agent, it makes quenched and tempered steels both harder and tougher and improves their strength at high temperatures. Molybdenum oxidizes at elevated temperatures.
It is used in nickel-based alloys that are heat and corrosion-resistant. The metal has been used for electrically heated glass furnace and fore hearth electrodes, in nuclear energy applications, and in aircraft and missile parts.
Molybdenum is an essential trace element for nitrogen fixation and other metabolic processes.
