As the European Union tries to reduce its dependence on Russian energy, the Russian president recently said Russia would try to shift its energy exports to the east, adding that there was no way for European countries to give up Russian gas immediately.

Russia supplies about 40 percent of the EU's gas, and western sanctions imposed over the conflict with Ukraine have complicated financing and logistical arrangements for existing agreements, hitting Russian energy exports, the report noted.  

Russia has been building closer ties with China and other Asian countries as the European Union debates whether to impose sanctions on Russian gas and oil and member states seek supplies from elsewhere, Reuters said.  

"So-called partners from unfriendly countries admit that they cannot survive without Russian energy, including gas," the Russian president said in a televised government meeting. There is no reasonable alternative to Russian gas in Europe right now."  

He also said Europe was driving up energy prices and destabilizing markets by talking about cutting off Russia's energy supplies. Russia, which produces about a tenth of the world's oil and a fifth of its natural gas, will need new infrastructure to increase energy supplies to Asia, he said.

He ordered Moscow to submit a plan by June 1, including "the expansion of transport infrastructure to countries in Africa, Latin America, and the Asia-Pacific region".  

He also sought to clarify the possibility of integrating two pipelines -- the Sakhalin-Khabarovsk-Vladivostok gas pipeline in the Far East and the "Power of Siberia" gas pipeline to China -- into Russia's unified gas supply system. In theory, connecting these routes to larger gas networks could allow Russia to divert gas from Europe to Asia.

Because of the ever-changing international situation, the supply and prices of international bulk molybdenum disulfide powder,Overview of molybdenum disulfide powder,Application of molybdenum disilicide powder,Molybdenum disilicide powder price,Molybdenum Disilicide Powder Supplier are still very uncertain.

Overview of molybdenum disulfide powder

Molybdenum disulfide is an inorganic substance. The chemical formula is MoS2, which is the main component of molybdenite. It is a black solid powder with metallic luster. The melting point is 2375 ℃, the density is 4.80g/cm³ (14 ℃), and the Mohs hardness is 1.0-1.5. Molybdenum disulfide begins to decompose at 1370 °C and decomposes into molybdenum metal and sulfur at 1600 °C. Molybdenum disulfide is oxidized when heated to 315 ℃ in air. Molybdenum disulfide is insoluble in water, dilute acid and concentrated sulfuric acid, generally insoluble in other acids, alkalis and organic solvents, but soluble in aqua regia and boiled concentrated sulfuric acid. Slow oxidation occurs at 400 ℃ to form molybdenum trioxide. Molybdenum disulfide can be heated to react with chlorine to form molybdenum pentachloride.

Molybdenum disulfide reacts with alkyl lithium under control to form an intercalation compound (intercalation compound) LixMoS2. If it reacts with butyllithium, the product is LiMoS2.

Molybdenum disulfide has a high active sulfur content, which tends to corrode copper and is discussed in many books and papers on lubricant additives. In addition, when parts made of copper and its alloys need to be lubricated, it is not necessary to choose lubricating products containing molybdenum disulfide, and copper corrosion inhibitors are also required.

Physical and chemical properties of molybdenum disulfide powder

Insoluble in water and dilute acid, it 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, and does not corrode rubber materials. It is a non-magnetic material and a compound with semiconductor properties. Molybdenum disulfide mo-S has many edges, easy to peel between layers, and has good anisotropy. S has strong adhesion to metal and can always adhere to the metal surface and play a lubricating role. Molybdenum disulfide used as lubricant has high compressive strength and wear resistance, excellent adhesion, low friction coefficient (0.03-10.08), film structure characteristics, film stability under high pressure; high lubricating performance at high temperature (1200℃), low temperature (-190℃), high speed, high pressure, ultra-low temperature, high vacuum conditions. Molybdenum disulfide begins to oxidize to molybdenum trioxide at 400 °C, and rapidly oxidizes to molybdenum trioxide above 540 °C. In an inert atmosphere, it sublimates at 450 °C, decomposes at 1370 °C, and decomposes into molybdenum and sulfur at 1600 °C. Molybdenum disulfide reacts with chlorine on heating to form molybdenum pentachloride; LiXMoS2 is an intercalated interlayer compound synthesized by controlled reaction with alkyl lithiums. Low toxicity.

Application of molybdenum disilicide powder

Molybdenum disilicide is used in high temperature anti-oxidation coating materials, electric heating elements, integrated electrode films, structural materials, composite material reinforcements, wear-resistant materials, and structural ceramic connecting materials. Distributed in the following industries:

1) Energy and chemical industry: electric heating elements, high temperature heat exchangers of atomic reactor devices, gas burners, high temperature thermocouples and their protective tubes, smelting vessels and crucibles (for smelting sodium, lithium, lead, bismuth, tin) and other metals ).

2) Microelectronics industry: MoSi2 and some other refractory metal silicides Ti5Si3, WSi2, TaSi2, etc. are important candidates for large-scale integrated circuit gate and interconnect films.

3) Aerospace industry: As a high temperature anti-oxidation coating material, it has been widely and deeply researched and applied. Especially as materials for turbine engine components such as blades, impellers, combustors, nozzles and seals.

4) Automobile industry: turbocharger rotors, valve bodies, spark plugs and engine parts for automobiles.

Molybdenum disilicide can also be used in the heating elements of ceramic heaters. Molybdenum silicide maintains good oxidation resistance by forming a protective film on the surface even at high temperatures of 1700°C. Molybdenum silicide is used as a structural material for high temperature components in aerospace and automotive gas turbines, gas combustion nozzles and high temperature filters.
