High Purity Molybdenum Disulfide MoS2 Powder CAS 1317-33-5, 99%
The price of nickel and stainless steel rose together. Nickel afternoon hand in hand with stainless steel together turn red up. Due to the temporary easing of geopolitical risks, risk assets are now picking up, nonferrous metals, stock markets, and so on have risen, the overall mood has temporarily improved. Ore prices are strong, the overlay of the epidemic on spot logistics or the formation of a certain impact. Phase, nickel and stainless steel materials to maintain high wide concussion pattern.
Nickel prices based on low inventory, tight supply and demand will still show high wide fluctuations. In addition, the current LME has low liquidity, so its sensitivity to capital will remain relatively high. Shanghai nickel-wide fluctuations are expected to continue in the 200,000-250,000 yuan wide repeated fluctuation trend. While stainless steel is affected by the stronger nickel pig iron, the cost support continues, but note that under the current demand is not effectively released, the upward space may also be affected, the stage is expected to fluctuate between 20000 and 22,000 yuan. The price of nickel produced such fluctuations, indicating that the price of the Molybdenum Disulfide may also be affected to a certain extent.
About Molybdenum Disulfide MoS2 Powder:
Molybdenum disulfide (MoS2) is the main component of molybdenite. Black solid powder with a metallic luster. Chemical formula MoS2, melting point 1185°C, density 4.80g/cm3 (14°C), Mohs hardness 1.0～1.5. It starts to decompose at 1370°C and decomposes into metallic molybdenum and sulfur at 1600°C. It starts to be oxidized when heated at 315°C in the air, and the temperature rises and the oxidation reaction accelerates. Molybdenum disulfide is insoluble in water, dilute acid and concentrated sulfuric acid. It is generally insoluble in other acids, alkalis and organic solvents, but it is soluble in aqua regia and boiling concentrated sulfuric acid. Slowly oxidized at 400 ℃ to generate molybdenum trioxide:
2MoS2+ 7 O2→ 2 MoO3 + 4 SO2 can be used to test the generated molybdenum trioxide with ferrotitanium reagent. First, the product is treated with sodium hydroxide or potassium hydroxide solution (the principle is to convert molybdenum trioxide into molybdate), and then the titanium iron reagent solution is added dropwise, which will react with the generated sodium molybdate or potassium molybdate to produce gold Yellow solution. This method is very sensitive, and trace amounts of molybdate can be detected. And if there is no molybdenum trioxide generated, the solution will not produce golden yellow, because molybdenum disulfide does not react with sodium hydroxide or potassium hydroxide solution.
Molybdenum disulfide can react with chlorine when heated to produce molybdenum pentachloride:
2 MoS2+ 7 Cl2→ 2 MoCl5+ 2 S2Cl2
Molybdenum disulfide and alkyl lithium react under control to form an intercalation compound (interlayer 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. It is discussed in many books and papers on lubricant additives. In addition, when the parts made of copper and its alloys need to be lubricated, it is not impossible to use molybdenum disulfide lubricating products, but also to add copper corrosion inhibitors.

Analysis of Molybdenum Disulfide MoS2 Powder:
How is Molybdenum Disulfide MoS2 Powder produced?
MoS2 can be prepared by the natural method, namely the molybdenite concentrate purification method, which is to remove the acid-insoluble matter in the molybdenite concentrate, SiO2, Fe, Cu, by subjecting high-quality molybdenum concentrate to certain physical and chemical actions. Ca, Pb and other impurities are further refined to obtain nano-MoS2. 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 most expensive MoS2 when working in ordinary atmosphere. It has lubricating ability below 1300℃, and it is recommended to use the cost-based MoS2.
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.
Applications of Molybdenum Disulfide MoS2 Powder:
Molybdenum disulfide is diamagnetic, can convert linear photoconductors and semiconductors with P-type or N-type conductivity, and has the functions of rectification and energy conversion.
Molybdenum disulfide can also be synthesized as a catalyst for hydrocarbon dehydrogenation.
Molybdenum disulfide is also known as "the king of advanced solid lubricants".
Molybdenum disulfide is a solid powder made from natural molybdenum concentrate chemically purified by changing the molecular structure.
Molybdenum disulfide has good dispersibility and does not need to be added. It can be added to various greases to form a colloidal state and will never replace it, thereby increasing the lubricity and extreme pressure of the grease.
Molybdenum disulfide is also suitable for high temperature, high pressure, high viscosity and high load mechanical working conditions to extend the service life of the equipment.
The main function of molybdenum disulfide as a friction material is to reduce friction at low temperatures, increase friction at high temperatures, and reduce combustion loss. Easily volatilize in the friction material.
Anti-friction: The size of disulfide particles formed by supersonic jet pulverization can reach 325-2500 mesh, the particle hardness is 1-1.5, and the friction coefficient is 0.05-0.1, so it can be used in friction materials to take advantage of the anti-friction effect;
Increased friction: Molybdenum disulfide is not conductive, and silicon carbide, molybdenum disulfide, molybdenum trisulfide and molybdenum trioxide are present. When the temperature of the friction material rises sharply due to friction, the shrinking molybdenum trioxide particles gradually heat up and expand, thereby increasing the friction in the axial direction.
Antioxidant: Molybdenum disulfide is obtained through a comprehensive chemical purification reaction, and its pH value changes 7-8, slightly alkaline. It covers the surface of the friction material, which can protect other materials from oxidation, especially making it difficult for other materials to move and enhancing adhesion.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.
The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.
Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.
U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.
The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."
The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled Molybdenum Disulfide are estimated to be influenced by international political situation changes.
