Molybdenum disulfide is the inorganic compound with the formula MoS2
What is Molybdenum disulfide?
Molybdenum Disulfide is a moderate water and acid-soluble Molybdenum source for uses compatible with sulfates. Sulfate compounds are salts or sulfuric acid esters formed by replacing one or both hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for water treatment, unlike fluorides and oxides, which tend to be insoluble. Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. Metallic ions can also be dispersed utilizing suspended or coated nanoparticles and deposited utilizing sputtering targets and evaporation materials for uses such as solar energy and fuel cells. Molybdenum Sulfide is generally immediately available in most volumes. Ultra-high purity and high-purity compositions improve optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions may be considered as alternative high surface area forms. American Elements produces many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural, and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopeia/British Pharmacopeia) and follows applicable ASTM testing standards. Additional technical, research, and safety (MSDS) information is available, as is a Reference Calculator for converting relevant units of measurement.
Molybdenum disulfide is the inorganic compound with the formula MoS2.
This black crystalline sulfide of molybdenum occurs as the mineral molybdenite. It is the principal ore from which molybdenum metal is extracted. MoS2 is relatively unreactive, being unaffected by dilute acids and oxygen. In its appearance and feel, molybdenum disulfide is similar to graphite. Indeed, like graphite, it is widely used as a solid lubricant because of its low friction properties and robustness. Molybdenum disulfide (MoS2 ). MoS2 has a low friction coefficient, but unlike graphite, it does not rely on adsorbed vapors or moisture. Adsorbed vapors may result in a slight but insignificant increase in friction. MoS2 also has greater load-carrying capacity, and its manufacturing quality is better controlled. Thermal stability in nonoxidizing environments is acceptable to 1100C (2012 °F), but in air, it may be reduced to 350 to 400 °C (662 to 752 °F).
Applications of Molybdenum disulfide
MoS2 with particle sizes of 1–100 µm is a common dry lubricant. Few alternatives can confer high lubricity and stability up to 350 °C in oxidizing environments. Sliding friction tests of MoS2 using a pin-on-disc tester at low loads (0.1–2 N) give friction coefficient values of <0.1. Molybdenum disulfide is often a component of blends and composites where low friction is sought. Various oils and greases are used because they retain their lubricity even in cases of almost complete oil loss, thus finding use in critical applications such as aircraft engines. MoS2 forms a composite with improved strength and reduced friction when added to plastics. Polymers filled with MoS2 include nylon (with the trade name Nylatron), Teflon, and Vespel. Self-lubricating composite coatings for high-temperature applications have been developed consisting of molybdenum disulfide and titanium nitride by chemical vapor deposition.
