• 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

  • Sulfur hexafluoride detection by Radar resonance enhanced

    In order to obtain a well defined spectral signature, the sulfur hexafluoride molecules are first dissociated by a focused pulsed Nd:YAG laser to sulfur difluoride molecules, which are then ionized by a pulsed, frequency tunable, narrow linewidth laser emitting in the ultraviolet. At the wavelength 269.5 nm, a concentration of 10 % of sulfur hexafluoride has been detected and the spectral signature shows some overlap with a carbon dioxide resonant spectral line.

    IDENTIFICATION: Sulfur hexafluoride is a colorless, odorless and tasteless gas. It can also be a liquid at extremely low temperatures. It is moderately soluble in water. It is a Greenhouse Gas which contributes to climate change. Sulfur hexafluoride is more effective at trapping heat than carbon dioxide. The Global Warming Potential of sulfur hexafluoride is quite high (25,000; the Global Warming Potential of CO2 is 1) and amongst the highest of all chemicals.
