Application of Tungsten silicide powder WSi2
1. Used as electric contact material, polycrystalline silicon shunt,
antioxidants covering layer and resistance wire application,etc.
2. MoSi2 Tungsten silicide powder is used for the heating element
of the ceramic heater.
Even at the high temperature of 1,700℃, it has maintains good
oxidation resistance by the formation of protective membrane on the
3. It is used in microeletronics as a contact material, with
resistivity 60–80 μΩ cm
4. It is often used as a shunt over polysilicon lines to increase
their conductivity and increase signal speed.
5. Tungsten silicide is a replacement for earlier tungsten films.
6. Tungsten silicide is also used as abarrier layer between silicon
and other metals,
7. Tungsten silicide also finds use in microeletromechanical
systems and for oxidation -resistant coatings.
8. Films of tungsten silicide can be plasma-etched using e.g.
nitrogen trifluride gas.
The storage method of Tungsten silicide powder WSi2
This product should be stored in dry, cool and sealing of the
environment, can not be exposure to air, in addition should avoid
the heavy pressure, according to ordinary goods transportation.
