Application

Sulphur hexafluoride is used as a plasma etching gas.

Sulphur hexafluoride is often used as a filling gas in double glazing as it reduces the sound transmissions and the heat transfer.

As sulphur hexafluoride is both inert and considerably denser than air it is suitable for blanketing open baths of certain molten metals, particularly magnesium.
