Molybdenum disulfide is a good solid lubricant that lubricates permanently in vacuum or air. The friction coefficient is relatively low, the air below 350℃ can be sustained lubrication. Using carbon brush additive, can effectively prolong the life of brush 15-20%. Molybdenum disulfide (MoS2 powder) is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is MoS2. Like most mineral salts, MoS2 has a high melting point but begins to sublime at a relatively low 450ºC. This property is useful for purifying compounds. In addition to its lubricity, MoS2 powder is also a semiconductor. It is also known that when doped with an electrostatic field, it and other semiconductor transition metal chalcogenides become superconductors on its surface. Molybdenum disulfide and related molybdenum sulfides are efficient catalysts for hydrogen evolution, including the electrolysis of water; thus, are possibly useful to produce hydrogen for use in fuel cells. MoS2 powder also possesses mechanical strength, electrical conductivity, and can emit light, opening possible applications such as photodetectors. MoS2 has been investigated as a component of photoelectrochemical (e.g. for photocatalytic hydrogen production) applications and for microelectronics applications.  Widely used in automobile industry and machinery industry carbon brush additives, added in lubricating oil, grease, polytetrafluoron, nylon, paraffin, stearic acid can improve lubrication and reduce friction effect. Can also be used for non-ferrous metal stripping agent and forging die lubricant, can effectively prolong the use of time, improve working conditions; Improve running-in operation state, prevent surface damage, prevent cold welding, ensure the best connection state when using thread connection; With some volatile solvents and can be sprayed metal surface or add engineering plastics to make lubrication elements. Electronics, spraying, electroplating, hardware, screws and other industries can directly use this kind of products.
