• Sulfur Hexafluoride and the Electric Power Industry

    S ulfur hexafluoride (SF 6) is a man-made gas that became commercially available in 1947 [1]. It is one of the most extensively and comprehensively studied molecular gases to date largely because of its many commercial and re-search applications. (Besides the use of sf 6 by the electric power industry, other uses include: semiconductor process-

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, 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. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of
