Global Molybdenum disulfide market trend 2024-2027 What is Molybdenum Disulfide? by Newsiberocruceros

Russia and Ukraine is an important exporters of oil, natural gas, metals, fertilizers, rare gases and other industrial raw materials. Affected by the further intensification of the tension of the war, the global market has become more worried about the supply of the Molybdenum disulfide, and panic spreads in the futures market. Prices of commodities such as aluminum and nickel are at recent highs on concerns that supplies will fall. Russia accounts for 49 percent of global exports of nickel, 42 percent of palladium, 26 percent of aluminum and 13 percent of platinum, and is a significant exporter of steel and copper. Palladium is an important metal for sensors and memory. In addition, Russia is the world's largest exporter of nitrogen fertilizer, the second largest exporter of potash fertilizer, and the third-largest exporter of phosphate fertilizer. Ukraine is also an important producer of nitrogen fertilizer. Russia's natural gas supply also has a significant impact on the global fertilizer industry and Molybdenum disulfide industry, especially in Europe. The price of the Molybdenum disulfide will also fluctuate to some extent. Russia carries out crude gas separation, and Ukraine is responsible for refined exports. Ukraine supplies 70% of the world's neon, 40% of krypton and 30% of xenon. These three gases are the materials used to make chips.

Introduction to Molybdenum Disulfide Powder
Molybdenum disulfide is a kind of inorganic. The chemical formula is MoS2, which is the main component of molybdenite. It is black solid powder with a metallic luster. The melting point is 2375, density is 4.80g/cm³ (14), and Mohs hardness is 1.0 ~ 1.5. 
Molybdenum disulfide begins to decompose at 1370and decomposes to molybdenum metal and sulfur at 1600. Molybdenum disulfide begins to be oxidized when heated in air at 315. Molybdenum disulfide is insoluble in water, dilute acid, and concentrated sulfuric acid, generally insoluble in other acids, bases, and organic solvents, but soluble in aqua regia and boiled concentrated sulfuric acid. Slow oxidation occurs at 400 and molybdenum trioxide is formed.
Molybdenum disulfide can be heated to react with chlorine gas to form molybdenum pentachloride.
Molybdenum disulfide reacts with alkyl lithium under control to form an embedded compound (intercalated compound) LixMoS2. If it reacts with butyllithium, the product is LiMoS2. 
Molybdenum disulfide has a high content of active sulfur, which is easy to cause corrosion to copper, which has been discussed in many books and papers about lubricant additives. In addition, when the parts of copper and its alloy manufacturing need lubrication, it is not necessary to choose lubrication products containing molybdenum disulfide, but also need to add an anti-copper corrosion agent.

Physicochemical Properties of Molybdenum Disulfide Powder
Molybdenum disulfide is insoluble in water and dilute acid, and can be corroded by concentrated sulfuric acid, concentrated nitric acid, boiling concentrated hydrochloric acid, aqua regia, pure oxygen, fluorine, and chlorine. It is insoluble in other acids, bases, solvents, petroleum, and synthetic lubricants. It has good chemical and thermal stability, cannot react with general metal surfaces, does not corrode rubber material, is a kind of non-magnetic material, and semiconductor properties compound. Molybdenum disulfide mo-S edge is quite many, easy to peel between layers, with good anisotropy, S has strong adhesion to metal, can adhere to the metal surface always play a lubrication function.  Molybdenum disulfide used as a lubricant has high compressive strength and wear resistance, excellent adhesion, low friction coefficient (0.03-10.08), film structure characteristics, the stable film under high pressure; It has high lubrication performance under high temperatures (1200), low temperature (-190), high speed, high pressure, ultra-low temperature, and high vacuum conditions. Molybdenum disulfide begins to oxidize to molybdenum trioxide at 400 and rapidly oxidizes to molybdenum trioxide above 540. It was sublimated at 450 in an inert atmosphere, decomposed at 1370℃, and decomposed into molybdenum and sulfur at 1600. Molybdenum disulfide and chlorine gas heating reaction to produce molybdenum penachloride; LiXMoS2, an embedded sandwich compound, was synthesized by controlled reaction with alkyl lithium.  Small toxicity.

Preparation Methods of Molybdenum Disulfide Powder
Natural law:
Molybdenum disulfide has excellent properties and broad application prospects, so the preparation and application of nano-mos2 have been studied a lot at home and abroad. 
MoS2 can be prepared by the natural method, that is, the molybdenite concentrate purification method. This method is to remove acid insoluble matter, SiO2, Fe, Cu, Ca, Pb and other impurities in molybdenite concentrate after certain physical and chemical action, and then further refine to obtain nano-mos2. The Us Climax Molybdenum company uses this method to produce MoS2. This method can maintain the natural MoS2 crystal shape, and good lubrication performance, so it is suitable for making lubricants. However, the purity of nano MoS2 produced by the natural method is not high, and the purification technology needs to be further improved. When the temperature is below 400 , it is recommended to use a low-cost MoS2 when working in an ordinary atmosphere. There is a lubrication capacity below 1300 , and it is recommended to use a low-cost MoS2. 
Chemical synthesis: 
The synthesis method can produce sulfide with high purity, few impurities, and fine particle size, and can produce sulfide with different functional requirements, so the synthesis method to produce nano sulfide has been paid much attention. There are many preparation methods of nano-MOS2, such as thermal decomposition method of ammonium tetrathiomolybdate, hydrogen sulfide or sulfur vapor reduction method, high-energy ball milling method, carbon nanotubes space limiting method, hydrothermal synthesis method, high-energy physical means and chemical method, etc. In general, there are two preparation methods: the tungsten source or molybdenum source can be directly reacted with the sulfur source to get nano-mos2, or the tungsten source or molybdenum source can be reacted with the sulfur source to get the precursor body, and then the precursor body can be decomposed or reduced to MoS2 by appropriate methods.

Applications of Molybdenum Disulfide Powder
1. Dry film lubricants. Molybdenum disulfide is used as lubricants in almost all dry film lubricants, such as EM-1 dry film (epoxy resin-MOS2 type), except in cases where black fillers are not specified. Common molybdenum disulfide dry film lubricants are the United States military dry film such as MIL-L-3987 and MIL-L-23398, are molybdenum disulfide dry film lubricants. At present, dry film lubricant has been widely applied to bearings, gears, molds, and other civilian products. 
2. Lubricants. Molybdenum disulfide ointment is generally added in oil and fat with a mass fraction of about 4% molybdenum disulfide. In metallurgy, steel rolling, mining machinery, and coal mining industry equipment have achieved a successful application. In some high temperature, open-air, field, tunnel application equipment, grease is difficult to lubricate or supplement equipment often use molybdenum disulfide oil paste. 
3. Lubricating film-forming paste for wheel, rail, and gear. The film-forming paste is also widely used in the lubrication of gear of locomotive drive shafts, cranes, steel rolling equipment, and large equipment such as mine. The life of rail can be increased 4 ~ 5 times by using film-forming paste on rail and rim. Rim life is increased by 7 times and electricity (or fuel) is saved by about 7%.
