Molybdenum disulfide is the inorganic compound composed of only two elements: molybdenum and sulfur. Its chemical formula is MoS. The compound is classified as a metal dichalcogenide. It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum. MoS2 is relatively unreactive. It is unaffected by dilute acids and oxygen
M 2315 (OTTO) Molybdenum disulphide, 99% Cas 1317-33-5 - used commonly as a dry lubricant. Molybdenum Disulfide can also be added to plastics to form composites with increased strength and less friction.
