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. The natural amorphous form is known as the rarer mineral jordisite. MoS2 is less reactive than other transition metal chalcogenides, being unaffected by dilute acids. 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, sometimes to relatively high temperatures. It also bonds very well to the surface of the metal. If used in a spray form it will dry after a few minutes and will be almost impossible to get off. It has a low coefficient of friction like Teflon but handles a lot wider range of temperatures. This is the first choice as a lubricant for bearings, Chains, Cables, and anything in motion.
