Global molybdenum disulfide MoS2 market trend 2023-2027 Preparation method and application of molybdenum disulfide MoS2 by Newscupcakemadrid

A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including molybdenum disulfide MoS2.

Molybdenum sulfide MoS2 power overview

Molybdenum disulfide MoS2 is an inorganic substance with the chemical formula MoS2, which is the main component of molybdenite. Black solid powder with metallic luster. Molybdenum disulfide is an inorganic substance with the chemical formula MoS2, which is the main component of molybdenum ore. Black solid powder with metallic luster and smooth hand feeling. The specific gravity is 4.8, and the Mohs hardness is 1 to 1.5. The general friction coefficient is 0.05~0.09. The oil absorption value is 1~1.5. Melting point is 1185℃, sublimation at 450℃. In the atmosphere, the temperature starts to oxidize gradually at about 400°C. As the particle size becomes finer, the oxidation temperature gradually decreases, and the oxide is molybdenum trioxide. Insoluble in dilute acid, dilute alkali, solvent, petroleum, synthetic grease. It can be corroded by aqua regia, concentrated sulfuric acid and boiling concentrated hydrochloric acid. Strong chemical and thermal stability. Does not chemically react with general metal surfaces and does not corrode rubber materials.

Preparation method of molybdenum disulfide MoS2 power

Natural law

Molybdenum disulfide has excellent properties and broad application prospects, so a lot of research has been done on the preparation and application of nano-MoS2 at home and abroad.

MoS2 can be prepared by the natural method, namely the molybdenite concentrate purification method, which is to remove the acid-insoluble matter, SiO2, Fe, Cu, Impurities such as Ca and Pb are further refined to obtain nano-MoS2. The American Climax Molybdenum Company has adopted this method to produce MoS2. The nano-MoS2 made by this method can maintain the natural MoS2 crystal shape, has good lubricating performance, and is suitable for making lubricants. However, the purity of the nano-MoS2 produced by the natural method is not high, and the purification technology needs to be further improved. When the temperature is lower than 400 ℃, it is recommended to use the lower cost MoS2 when working in the ordinary atmosphere. It has lubricating ability below 1300 ℃, and it is recommended to use the lower cost MoS2.

Chemical synthesis

The synthetic method can produce sulfides with high purity, less impurities, and fine particle size, and can prepare sulfides that meet different functional requirements. Therefore, the production of nano sulfides by synthetic methods has always attracted much attention. There are many methods for preparing nano-MoS2, such as ammonium tetrathiomolybdate thermal decomposition method, hydrogen sulfide or sulfur vapor reduction method, high-energy ball milling method, carbon nanotube space confinement method, hydrothermal synthesis method, high-energy physical method and chemical method combination and many more. In general, there are two preparation methods. You can directly react a tungsten source or a molybdenum source with a sulfur source to obtain nano-MoS2, or first react a tungsten source or a molybdenum source with a sulfur source to obtain a precursor, and then pass the precursor through an appropriate Method to decompose or reduce to MoS2.

Application of Molybdenum sulfide MoS2 power

Molybdenum disulfide MoS2 is an important solid lubricant, especially suitable for high temperature and high pressure. It is also diamagnetic, can be used as a linear photoconductor and a semiconductor showing P-type or N-type conductivity, and has a rectifying and energy function. Molybdenum disulfide can also be used as a catalyst for the dehydrogenation of complex hydrocarbons.

Also known as "the king of advanced solid lubricants." Molybdenum disulfide is a solid powder made from natural molybdenum concentrate through chemical purification and changing the molecular structure. This product is black, slightly silver-gray, metallic luster, smooth to the touch, insoluble in water. This product has the advantages of good dispersibility and non-stickiness. It can be added to various greases to form a non-stick gel state, which can increase the lubricity and extreme pressure of the grease. It is also suitable for high-temperature, high-pressure, high-speed, and high-load mechanical working conditions to extend the life of the equipment. The main function of molybdenum disulfide in friction materials is to reduce friction at low temperatures and increase friction at high temperatures, resulting in a small loss on ignition. It is volatile in friction materials.

Anti-friction properties: MoS2 grinded by supersonic jet has a particle size of 325-2500 mesh, particle hardness of 1-1.5, and friction coefficient of 0.05-0.1, which can reduce friction when used in friction materials;

Increase friction: Molybdenum disulfide MoS2 does not conduct electricity. There are copolymers of molybdenum disulfide, molybdenum trisulfide and molybdenum trioxide. When the friction material rises sharply due to friction, the molybdenum trioxide particles in the copolymer expand with the increase in temperature to increase the friction;

Anti-oxidation: MoS2 is obtained by chemical purification and comprehensive reaction. Its PH value is 7-8, which is slightly alkaline. It covers the surface of the friction material to protect other materials and prevent them from being oxidized, especially to prevent other materials from falling off and enhance adhesion;

In addition, molybdenum disulfide MoS2 can also become a new material for making transistors. Compared with graphene, which is also a two-dimensional material, the energy band gap of molybdenum disulfide is 1.8 eV, while graphene has no energy band gap. Therefore, molybdenum disulfide may have a broad application space in the field of nano-transistors. Moreover, the electron mobility of a single-layer molybdenum disulfide transistor can reach about 500 c㎡/(V•s), and the current switching rate can reach 1×10^8.
