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.

New Delhi: India is seeking to increase its purchases of crude oil from Brazil, the country's oil minister said recently after meeting his Brazilian counterpart.
India is the world's third-largest importer and consumer of crude oil. Brazil currently supplies only a fraction of India's crude oil imports.
India's state-owned companies Bharat Petroleum Corp and Oil and Natural Gas Corp have invested in oil and gas exploration in Brazil.
India, which imports about 84% of its crude oil needs, is reducing its import bill by increasing biofuel use, among other things.
India's state-owned fuel retailers are increasing ethanol storage capacity by 51 percent and the country plans to double the biofuel blend in petrol to 20 percent by 2025.
India and Brazil are currently cooperating on biofuels and ethanol.
The prices of many commodities like the tungsten silicide, tungsten silicide overview, tungsten silicide application, tungsten silicide suppliers, tungsten silicide price are expected to increase in the future.
