[contradictory] Molybdenum is also used to enhance the corrosion resistance of ferritic (for example grade 444) [63] and martensitic (for example 1.4122 and 1.4418) stainless steels. [citation needed] Because of its lower density and more stable price, molybdenum is sometimes used in place of tungsten. [52]
Molybdenite is an important ore of molybdenum, and is the most common source of the metal. [4] While molybdenum is rare in the Earth's crust, molybdenite is relatively common and easy to process, and accounts for much of the metal's economic viability. Molybdenite is purified by froth flotation, and then oxidized to form soluble molybdate ...
It is also used to construct valves for molten zinc. [11] Molybdenum is used in mercury wetted reed relays, because molybdenum does not form amalgams and is therefore resistant to corrosion by liquid mercury. [12] [13] Molybdenum is the most commonly used of the refractory metals. Its most important use is as a strengthening alloy of steel.
This metal is commonly used instead of 300 series stainless steels in high temperature and low pH applications in food processing. For example, tomato juice will corrode 316L stainless steel at pasteurization temperatures of 100 °C (210 °F). AL-6XN will better resist this corrosion while still offering the beneficial properties of stainless ...

The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
The agriculture industry uses 500 tons per year as a fertilizer. In particular, its use has been suggested for treatment of whiptail in broccoli and cauliflower in molybdenum-deficient soils. [4] [5] However, care must be taken because at a level of 0.3 ppm sodium molybdate can cause copper deficiencies in animals, particularly cattle. [3]
Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is MoS 2 . The compound is classified as a transition metal dichalcogenide .
