Molybdenum Mo PubChem

Molybdenum (Mo) is a refractory metallic element used principally as an alloying agent in steel, cast iron, and superalloys to enhance hardenability, strength, toughness, and wear and corrosion resistance.To achieve desired metallurgical properties, molybdenum, primarily in the form of molybdic oxide or ferromolybdenum, is frequently used in combination with or added to chromium, manganese ...

Molybdenum Wikipedia

Characteristics Physical properties. In its pure form, molybdenum is a silvery-grey metal with a Mohs hardness of 5.5 and a standard atomic weight of 95.95 g/mol. It has a melting point of 2,623 C (4,753 F); of the naturally occurring elements, only tantalum, osmium, rhenium, tungsten, and carbon have higher melting points. It has one of the lowest coefficients of thermal expansion among ...

Molybdenum Oxide MoO3 Nanoparticles Properties

Molybdenum does not occur naturally as a free metal on Earth. Molybdenum oxide nanoparticles are graded as harmful and can affect the skin and eyes. It may also cause cancer. Molybdenum oxide nanoparticles appear in a powder form. Chemical Properties. The chemical properties of molybdenum oxide nanoparticles are outlined in the following table.

Electronic properties of reduced molybdenum oxides

The electronic properties of MoO 3 and reduced molybdenum oxide phases are studied by density functional theory (DFT) alongside characterization of mixed phase MoO x films. Molybdenum oxide is utilized in compositions ranging from MoO 3 to MoO 2 with several intermediary phases. With increasing degree of reduction, the lattice collapses and the layered MoO 3 structure is lost.
