  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride is inert in the troposphere and stratosphere and is extremely long-lived, with an estimated atmospheric lifetime of 800–3,200 years. [29] Measurements of SF 6 show that its global average mixing ratio has reached over 10 parts per trillion (ppt) as of April 2020, and is increasing by about 0.35 ppt (3.5 percent) per year.

  • The Absorption Spectrum of Sulfur Hexafluoride in the Vacuum

    The spectrum of sulfur hexafluoride has been investigated down to wavelengths about 600A. The maximum of the first electronic transition is found at about 1050A. Three other transitions occur between this wavelength and 802A, where strong continuous absorption begins, and nothing further can be resolved at shorter wavelengths. Qualitative suggestions are offered about the dissociation of SF

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6 ) gas to cool and quench the arc on opening a circuit.
