As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.
For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.
Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the molybdenum disulfide MoS2 in the chemical industry will also be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the 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
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.
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.
