  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.

    Sulfur hexafluoride (SF6) is an inert, volatile tracer and has been deliberately added to water bodies to determine kw. Experiments in enclosed lakes showed a good correlation between kw and wind speed and a parameterization of kw developed from these studies predicts a similar global mean (12 cm h −1) to that obtained from the radon data.
