About Tungsten Silicide WSi2 Powder
:
Tungsten silicide (WSi2)
A silicide is an inorganic tungsten compound. It is a conductive, ceramic material.
Tungsten silicide
Fluorine, halogens, strong acids and oxidants all react violently.
WSi2
The coating is effective as a protective layer. Similar to Molybdenum Disilicide MoSi2, its high emissivity makes it a good coating for applications.
tungsten disilicide
The material's ability to radiate heat at high temperatures makes it attractive as a heat-shield.
Silicide
Microelectronics uses it as a material for contact, with a resistivity between 60 and 80mOcm. It is often used to improve the conductivity of wires made from polysilicon and to speed up signal transmission. By using monosilane (or dichlorosilane) and tungsten Hexafluoride, the silicide can be prepared through chemical vapor deposit. The deposited film has a non-stoichiometric structure and needs to be annealed in order to become stoichiometric.
Tungsten silicide
This is an alternative to the early tungsten-based film.
Tungsten silicide powder
can also be used in microelectromechanical systems and oxidation-resistant coatings.

How is Tungsten Silicide WSi2 Powder produced?
Tungsten powder and silicon powder are used as raw materials for synthetic silicide tungsten powder. They have an average of 24 hours in acetone. The starting powder is used in the measurement of thermal measurements, while the powder is 5: 1. Dry substances and dried, acetone evaporation. The preparative mixture was heat-treated at different temperatures at 50 deg C at different temperatures of 1250 to 1400 deg C. The heating rate is 10k * min -1. The mixture was placed in a tube furnace and heat treatment was carried out in an argon flow for 4 hours. After the heat treatment is over, the furnace is cooled to room temperature.
Application of Tungsten Silicide WSi2 Powder
:
Tungsten silicide WSi2 powder is used in microelectronics as an electric shock material, shunting on polysilicon wires, anti-oxidation coating and resistance wire coating. Tungsten silicide is used as a contact material in microelectronics, with a resistivity of 60-80mOcm; it is formed at 1000degC. It is usually used as a shunt for polysilicon lines to increase their conductivity and increase signal speed. The tungsten silicide layer can be prepared by chemical vapor deposition, such as vapor deposition. Use monosilane or dichlorosilane and tungsten hexafluoride as raw material gas. The deposited film is non-stoichiometric and requires annealing to transform into a more conductive stoichiometric form.
Tungsten silicide can replace the early tungsten film. Tungsten silicide is also used as a barrier layer between silicon and other metals.
Tungsten silicide is also very valuable in micro-electromechanical systems, in which tungsten silicide is mainly used as a thin film for the manufacture of microcircuits. For this purpose, a film of tungsten silicide can be plasma-etched using, for example, silicide.
