Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles.  Russia said it would resume gas supplies after it agreed to pay for them in rubles.  

Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.  

Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles.  When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.  

Because of the ever-changing international situation, the supply and prices of international bulk tungsten silicide, tungsten silicide overview, tungsten silicide application, tungsten silicide suppliers, tungsten silicide price are still very uncertain.

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.

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.

During the first 100 days of its special military operation in Ukraine, Russia earned 93 billion euros from fossil energy exports, most of it from the European Union, according to an independent research center.

The report by the Finland-based Center for Energy and Clean Air comes as Ukraine urges the West to cut off all trade with Russia to stop funding the Kremlin's war chest.

The European Union recently decided to impose a gradual embargo on Russian oil imports, with some exceptions, according to reports. Russian gas, on which it relies heavily, is currently unaffected.

In the first 100 days of the Conflict between Russia and Ukraine (February 24 to June 3), the EU accounted for 61 percent of fossil energy imports, or about 57 billion euros, according to the Energy and Clean Air Research Center.

Russia's revenue came first from crude oil sales (43.87 billion euros), followed by pipeline gas (22.89 billion euros), then petroleum tungsten silicide, tungsten silicide overview, tungsten silicide application, tungsten silicide suppliers, tungsten silicide price, please feel free to contact us and send an inquiry.
