Tungsten silicide WSi2 powder action
Silicides are used as contact materials in microelectronics with resistivity of 60-80μΩcm.Form 1000 ℃.It is commonly used as a shunt for polysilicon wires to increase their electrical conductivity and signal speed.Silicide layers can be prepared by chemical vapor deposition, for example, using methylsilane or dichlorosilane and tungsten hexafluoride as feedstock gases.The deposited film is non-stoichiometric and requires annealing to be converted to a more final stoichiometric form.Tungsten silicide can replace the earlier tungsten film.Tungsten silicide can also be used in microelectromechanical systems and oxidation resistant coatings.
Functional application of tungsten silicide WSi2 powder
Tungsten silicide WSi2 powders are used as electric shock materials in microelectronics, for shunting on polysilicon conductors, oxidation resistance coating and resistance conductor coating.Tungsten silicide is used as a contact material in microelectronics with a resistivity of 60-80μΩcm.It's formed at 1000 degrees Celsius.It is commonly used as a shunt for polysilicon wires to increase their electrical conductivity and signal speed.The tungsten silicide layer can be prepared by chemical vapor deposition such as vapor deposition.Methylsilane or dichlorosilane and tungsten hexafluoride are used as feedstock gas.The deposited film is non-stoichiometric and requires annealing to be converted to a more conductive stoichiometric form.
Tungsten silicide can replace older tungsten films.Tungsten silicide is also used as a barrier between silicon and other metals.
Tungsten silicide is also valuable in microelectromechanical systems, where it is used primarily as a thin film for making microcircuits.For this purpose, tungsten silicide films can be plasma etched using, for example, silicides.

What knife is used to turn tungsten silicide material
As a kind of superhard cutting tool material, diamond has been widely used in cutting. The high price of natural diamond limits the development of diamond cutting tools. In the 1970s, polycrystalline diamond (PCD) was synthesized by using high-pressure synthesis technology, which solves the problem of scarce and high price of natural diamond.The application range of diamond tools is extended to aviation, aerospace, automobile, electronics, stone and other fields.
Polycrystalline diamond (PCD) tool is mainly used for processing non-ferrous metals and other non-ferrous metals. It can grind out a very sharp edge and get a better processing surface. It is also the preferred material for processing new non-metallic materials, and can cut hard alloy and industrial ceramics and other high hardness products.
