• 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

  • Quantitative analysis of decomposition products of sulfur

    Electrical utilities use sulfur hexafluoride (SF<SUB6</SUB) as an electrical insulator in many components of their power systems. Under normal conditions SF<SUB6</SUB is stable, but in electrical discharges SF<SUB6</SUB decomposes into many byproducts. With an FT-IR spectrometer and a 20-m cell, we have examined the byproducts from various discharges and obtained quantitative analyses of
