  • 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.

    Abstract. Sulfur hexafluoride (Sulfr hexafluoride) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, gaz sf6 emissions from China were inventoried for 1990-2010 and projected to 2020. Results reveal that the highest sf6 gas emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the Sulfr hexafluoride production sector (each about 10%).
