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 Tungsten Disulfide,Overview of Tungsten Disulfide,Application of Tungsten Disulfide,Tungsten disulfide powder price,Tungsten Disulfide Supplier may also be affected to a certain extent.
Overview of Tungsten Disulfide
Tungsten disulfide as a potential battery material is also expected to benefit from more market replenishment.
Tungsten disulfide is a layered material with remarkable surface effects, electron mobility, thermochemical stability and high electron density of states. It has been widely used for lithium and sodium storage. For example, nanocomposites as conductive additives or graphene composites as battery cathode materials can exhibit higher specific capacity and discharge efficiency, making up for the deficiencies of single-component WS2 or C as anode materials.
The advent of sodium batteries is expected to alleviate the current shortage of lithium resources on the rapid development of the new energy industry, and will further stimulate the application of transition metal dichalcogenides such as tungsten disulfide WS2 in the field of power storage.
Lithium-ion batteries are a key raw material for developing energy devices and realizing the vision of "carbon neutrality". However, the current capital investment on the raw material side is difficult to cover the rapidly growing energy demand, and there is an obvious structural imbalance in the investment in the lithium battery industry chain, resulting in the rising cost of lithium raw materials.
So, sodium batteries are starting to come into view. Sodium is abundant in nature, and as an energy material, it also has large capacity and high rate performance, which can effectively make up for the shortcomings of lithium-ion batteries in the current energy storage field. Although the current price of sodium batteries is higher than that of lithium batteries due to the small scale of the supply chain, as the technology matures, cost-effective sodium batteries will become an effective supplement to lithium batteries, and it is even expected to serve the development of new energy fields together with lithium batteries.
Graphene is a novel anode material that has been most studied by energy storage researchers in recent years. It has many advantages, such as excellent electrical and thermal conductivity, large specific surface area, etc. However, as an energy storage material, it still makes up for its own shortcomings, such as the material is prone to structural collapse under long cycles, resulting in a serious decline in battery capacity. Therefore, graphene and WS2 nanomaterials with high thermochemical stability can effectively make up for the deficiency of graphene.
In general, tungsten disulfide is an ideal choice for battery materials.
Application of Tungsten Disulfide
Tungsten disulfide can be used as a lubricant, and its performance is better than that of molybdenum disulfide, with a lower coefficient of friction and higher compressive strength. Stand alone equipment for high temperature, high pressure, high speed, high load and operation in chemically active media. Lubricants formulated with other materials for forging and stamping can prolong die life and improve product finish. Filler material configured with PTFE and Nylon for the manufacture of self-lubricating parts. In addition, tungsten disulfide can also be used as a catalyst in the petrochemical industry, which has the advantage of cracking tungsten disulfide. (WS2) or tungsten disulfide is a very smooth dry film friction coating. WS2 is extremely low, at 0.03, lower than PTFE, graphite or molybdenum disulfide (MoS2). It has unmatched performance in lubricity, non-stick, low friction, wear life and size ratings compared to many other WS2s. It has a wide range of applications in transistors, sensors, photocatalysis, electronic equipment and other fields. Tungsten disulfide powder has good solubility in water and ethanol.
WS2 is an excellent release material for plastic molds, extrusion dies and other release applications.
WS2 can save hydraulic oil and can also be used with petrochemical oil, grease, synthetic oil, silicone oil valve and hydraulic oil. It has affinity for the liquid layer and keeps the liquid layer. surface, thereby further improving the lubrication effect. Small parts can be coated without tolerance issues when the thickness is less than 1 micron.
WS2 is also a fairly inert and non-toxic material that has been used in medical devices and food processing applications.
WS2 replaces customer substrates with high-speed processing at ambient temperatures. It will not make the substrate continuous or warp.
WS2 can be used alone or in combination with our PVD hardcoats for increased durability, high performance, stable and reliable catalytic activity, and long service life.

Greece will hand over Iranian oil it intercepted from a Russian-flagged tanker to the United States at the request of the U.S. Justice Department, Greek port police said recently, AFP reported. The decision angered Tehran.
In April, Greek authorities reportedly seized a Russian oil tanker, the Pegas, which was said to be heading to the Turkish port of Marmara.
Reports say the ship was docked in Calistos Bay with a crew of several people said to be Russian. The Greek coast guard said the ship had been renamed the Lana.
The report notes that the European Union imposed sanctions on Russia after the conflict broke out in February. Greek authorities seized the tanker in accordance with European Union sanctions.
According to information at the time, the tanker was carrying 115,000 tons of Iranian oil.
Iran's Ports and Maritime Organization strongly protested Greece's decision, calling it an "international bandit." "The Islamic Republic of Iran will not give up its legitimate rights and expects the Greek government to abide by its international obligations in the area of navigation and shipping," it said in a statement on its website.
Iran's Foreign Ministry, through the International Maritime Organization, called on the Greek government to release the tanker and its crew overnight, adding that "the Americans discharged their cargo," the report said.
Athens did not immediately respond to the Iranian protest and gave no further details about the oil on board or how it was handed over to the United States, the report said.
