  • 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

  • Sulfur hexafluoride | F6S - PubChem

    Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).
