SF6 gas Mixtures maintenance station

Sep 20, 2019Why worry, leaks!. The discovery of SF 6 can be traced to the work of Henri Moissan and Paul Lebeau in 1901, who found that sulfur reacted with fluorine according to the reaction equation: . S 8(s) + 24 F 2(g) → 8 SF 6(g). Under ambient conditions of temperature and pressure, SF 6 exists as a gas; this property is traceable to the small size and low polarizability of the fluorine atoms ...

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made and naturally occuring 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.
