Specification of Tungsten silicide powder WSi2

Brand            Chemical composition %
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 surface.

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.
