Applications
  • Semiconductors
    Semiconductors

    Sulphur hexafluoride is used as a plasma etching gas.

  • Glass
    Glass

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

  • Metal Treating
    Metal Treating

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

  • Scientific Experiments
    Scientific Experiments

    Sulphur hexafluoride is used in laboratories as a carrier gas media in supercritical fluid chromatography (SFC), and as media in supercritical fluid extraction (SFE) for sample preparation.
