Description

 

1.Tungsten(VI) fluoride, also known as tungsten hexafluoride, is the inorganic compound of tungsten andfluorine with the formula WF6.

2.This corrosive, colorless compound is a gas under standard conditions, with a density of about 13 g/L (roughly 11 times heavier than air),

3.WF6 is one of the heaviest known gases under standard conditions.

4.WF6 gas is most commonly used in the production of semiconductorcircuits and circuit boards through the process of chemical vapor deposition – upon decomposition, molecules of WF6 leave a residue of metallic tungsten.

 

Usage

 

In the fluoride of tungsten, WF6 is the only production which is stable and industrialized. Tungsten hexafluoride is used in chemical vapor deposition process as the materials. WSi2 which is produced by tungsten hexafluoride can be used in the Large Scale Integration as the wiring materials. The multiplex metals of tungsten and rhenium can be used in X-ray as the emissive electrode. In the electron industry tungsten hexafluoride also can be used in the semi-conductor.

In other industry tungsten hexafluoride also has many uses. It can produce firm tungsten carbide by CVD process. Tungsten hexafluoride also can be used to produce tungstenic materials such as tungsten pipe and crucible.
