Discovered:
Carl W. Scheele extracted molybdenum oxide from the mineral molybdenite (molybdena) in 1778. He concluded that the mineral contained a new element but did not isolate it. In 1781, Peter J. Hjelm isolated the metal by reducing the oxide with carbon. The element name comes from the Greek word 'molybdos', meaning lead.
Characteristics:
Molybdenum is a silvery-white, high-melting metal.
It does not react with oxygen or water at room temperature and it also resists corrosion at ordinary temperatures.
Molybdenum is one of the five major refractory metals (metals with very high resistance to heat and wear). The other refractory metals are tungsten, tantalum, rhenium and niobium.
Molybdenum oxide (MoO3) is soluble in alkaline water, forming molybdate salts.
Uses:
Molybdenum's strength and resistance to expanding or softening at high temperatures is particularly sought after in critical areas where high temperatures are common, such as in nuclear power plants and aircraft engines. It is also used in the petroleum industry, to catalyze the removal of organic sulfur compounds in coal liquification and gas liquification processes.
Molybdenum is an essential trace element for animals and plants. As with selenium, too much of it is toxic, too little of it is fatal.
In nitrogen fixing bacteria, molybdenum is a vital component of the nitrogenase enzyme which allows conversion of nitrogen gas in air into nitrates vital for plant growth.
Molybdenum is also present in 20 or so enzymes needed in animals' metabolisms.
We are in the position of producing all Grades of Molybdenum in according with ASME standards equivalents.
