Description of disulfuredemolybdene,

• Molybdenum disulfide is the inorganic compound composed of only two elements: molybdenum and sulfur. Its chemical formula is MoS 2.
  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. MoS 2 is relatively unreactive. It is unaffected by dilute acids and oxygen. In appearance and feel, molybdenum disulfide is similar to graphite. It is widely used as a solid lubricant because of its low friction properties and robustness. Bulk MoS 2 is a diamagnetic, indirect bandgap semiconductor similar to silicon, with a bandgap of 1.23 eV.

What is Molybdenum disulfide ?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Molybdenum disulfide   which has developed particularly rapidly in recent years. Do you know about Molybdenum disulfide?
• The official answer：Black powder with silvery-gray luster. Crystallized in the hexagonal crystal system. Insoluble in water, dilute acid, and concentrated sulfuric acid, but soluble in hot sulfuric acid. Insoluble in other acids, alkalis, solvents, petroleum, synthetic lubricants, molybdenum disulfide, the main component of molybdenite, lead-gray to black solid powder, slippery in contact, odorless, belonging to the hexagonal crystal system or rhombohedral crystal system, similar to graphite, with a metallic luster; molybdenum disulfide is a good solid lubricating material, in high temperature, low temperature, high load, high speed, with chemical corrosion and modern super vacuum and other conditions It has excellent lubricity for equipment.

What’s the application of Molybdenum disulfide ?

Dry film lubricant except for the case that black filler cannot be used, molybdenum disulfide is used as a lubricant in almost all dry film lubricants, such as EM-1 dry film (epoxy resin – MoS2 type). The common molybdenum disulfide dry film lubricants are American military dry film such as MIL-L-3987 and MIL-L-23398, which are molybdenum disulfide dry film lubricants, SS-2 dry film lubricant developed by domestic silicate as a binder, and PEP lubricated rustproof dry film with phenolic oxygen resin as a binder is also a dry film made of molybdenum disulfide as a main lubricant and other fillers. At present, dry film lubricant has been promoted to bearings, gears, molds, and other civilian products.2. Lubricating oil paste molybdenum disulfide paste, generally in oil, grease with a mass fraction of about 4% of molybdenum disulfide. It has been successfully applied to the equipment in metallurgy, steel rolling, mining machinery, and the coal mining industry. In some high temperature, open-air, field, pit application equipment, grease is difficult to lubricate or supplement the equipment often use molybdenum disulfide grease. Shanghai, Benxi, and other places to produce No. 9, No. 2 oil paste that belongs to this category. 3. wheel rails, gears with lubricating film-forming paste Chinese Academy of Sciences Lanzhou Institute of Chemical Research successfully developed GM type, BL type lubricating film-forming paste, eliminate the gearbox oil leakage, this film-forming paste is also promoted to locomotive drive shaft gear, crane, steel rolling equipment and mining and other large equipment gear lubrication. The application of film-forming paste on steel rails and wheel rims can increase the life of rails by 4-5 times; the life of wheel rims by 7 times, and save about 7% of electricity (or fuel). About molybdenum disulfide overview, physical and chemical properties, preparation methods, production standards, applications are edited and compiled by Ding Hong of Chemical book. (2015-10-23)
