Russia's insistence on paying for Russian gas in rubles has rattled European countries: Greece held an emergency meeting of suppliers, the Dutch government would urge consumers to use less gas, and the French energy regulator told consumers not to panic. Russian gas meets one-third of Europe's annual energy needs.
Russia said they could expand their demand for ruble payments for other commodities, including oil, grain, fertilizer, coal, and metals, which raised the risk of recession in Europe and the US.
Moscow is expected to unveil its ruble payment plan in early April, but it said it would not immediately ask buyers to pay for gas in rubles.
Western countries have said paying in rubles would be a breach of contract, and renegotiation could take months or longer. This uncertainty has pushed commodity market prices higher.
The supply and prices of other commodities like the tungsten silicide, tungsten silicide overview, tungsten silicide application, tungsten silicide suppliers, tungsten silicide price could also be affected.
Overview of tungsten silicide WSi2 powder
Tungsten silicide are used as contact materials in microelectronics and have a resistivity of 60-80 μΩcm. It forms 1000°C. It is often used as a shunt for polysilicon wires to increase their conductivity and increase signal speed. The silicide layer can be prepared by chemical vapor deposition, for example, using monosilane or dichlorosilane and tungsten hexafluoride as raw material gases. The deposited films are non-stoichiometric and require annealing to convert to a more final stoichiometric form. Tungsten silicide can replace earlier tungsten films. Tungsten silicide can also be used in MEMS and anti-oxidation coatings.
Tungsten Silicide Properties
Blue-gray tetragonal crystal, melting point>900℃, compound Tungsten Silicide (WSi2)
Preparation method of tungsten silicide
(1) Mix tungsten powder and silicon powder in a molar ratio of 1:2, and mix titanium powder and graphite powder in a molar ratio of 1:1, and then mix them evenly.
(2) The W-Si mixed powder is placed in the center of the crucible, and the Ti-C mixed powder is evenly placed between the W-Si mixed powder and the crucible. Finally, a layer of Ti-C mixed powder is placed on top of all the mixed powders. The weight ratio of the loaded Ti-C mixed powder and W-Si mixed powder is (0.8~1.2): 1
(3) Put the crucible containing the mixed powder into a closed reactor, fill it with argon after vacuuming, and then energize the mixture with tungsten wire to initiate the reaction between the mixed materials.
(4) After cooling, take out the reacted material, separate titanium carbide and tungsten disilicide, and crush them respectively to obtain titanium carbide and tungsten disilicide powder.
Application of tungsten silicide WSi2 powder
Tungsten silicide WSi2 powder is used in microelectronics as electrical shock material, shunting on polysilicon wires, anti-oxidation coatings and resistance wire coatings. Tungsten silicide is used as a contact material in microelectronics with a resistivity of 60-80 μΩcm. It forms at 1000°C. It is often used as a shunt for polysilicon wires to increase their conductivity and increase signal speed. The tungsten silicide layer can be prepared by chemical vapor deposition, such as vapor deposition. Monosilane or dichlorosilane and tungsten hexafluoride are used as raw material gases. The deposited films are non-stoichiometric and require annealing to convert to a more conductive stoichiometric form.
Tungsten silicide can replace earlier tungsten films. Tungsten silicide also acts as a barrier between silicon and other metals.
Tungsten silicide is also valuable in microelectromechanical systems, where tungsten silicide is primarily used as a thin film for making microcircuits. For this purpose, the tungsten silicide film may be plasma etched using, for example, silicide.

|Tungsten Silicide Health & Safety Information|
The day after the shooting at a Texas elementary school, the National Rifle Association issued a statement saying it "extends its deepest sympathies to the families and victims involved in this terrible and evil crime," adding it would "reflect on these events and pray for the victims."
It comes just days before the National Rifle Association's annual convention in Houston, Texas. Houston is less than five hours away. Texas Governor Tony Abbott, Senator Ted Cruz, and others are scheduled to attend the event, which has also caused a lot of controversies.
Texas Democratic gubernatorial candidate Mark O 'Rourke took to social media to call on Abbott to pull out of the convention, urging that it be held outside Texas. Many American netizens also took to social media to express their dissatisfaction. "I wish the NRA's annual meeting was held three days after 19 children and two adults were massacred," said one. "The school shooting was not a lone Wolf, but with the help of the NRA."
Between 2000 and 2020, US gun manufacturers produced more than 139 million guns for the civilian market, according to the Justice Department report. The NATIONAL Rifle Association (NRA) is one of the leading gun rights advocates with more than 5m members and deep pockets. The United States has not passed major gun control laws for more than two decades, blocked by gun interests.
