Molybdenum disulfide is the inorganic compound with the formula MoS2. This black crystalline sulfide of molybdenum occurs as the mineral molybdenite. Molybdenum disulfide is the principal ore from which molybdenum metal is extracted. The natural amorphous form is known as the rarer mineral jordi site. 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. Molybdenum disulfide is often a component of blends and composites where low friction is sought.
