Molybdenum has a very high melting point, so it is produced and sold as a gray powder. Many molybdenum articles are formed by compressing the powder at very high pressure.
Most molybdenum is used to make alloys. It is used in steel alloys to increase strength, hardness, electrical conductivity, and resistance to corrosion and wear. These “molybdenum steel” alloys are used in engine parts. Other alloys are used in heating elements, drills, and blades.
Molybdenum bisulphide is used as a lubricating additive. Other uses of molybdenum include catalysts for the oil industry, inks for circuits, pigments, and electrodes.
Although it is toxic in anything that is not a small amount, molybdenum is an essential element for animals and plants.
There are about 50 different enzymes used by plants and animals that contain molybdenum. One of these is nitrogenase, which is found in nitrogen-fixing bacteria that make nitrogen available to plants. Legumes have radical nodules that contain these nitrogen-fixing bacteria.
The main molybdenum ore is molybdenite (molybdenum disulfide). It is processed by roasting to form molybdenum oxide and then reduced to metal. The main mining areas are located in the United States, China, Chile, and Peru. A part of molybdenum is obtained as a by-product of tungsten and copper production. The world production is around 200,000 tons per year.
