sf6 Gas Mixture emission for mining

Sulfur hexafluoride (sf 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made and naturally occuring greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. sf6-gas has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.

  • A review on SF6 substitute gases and research status of

    Nov 01, 2018SF 6 gas is widely used in electric power apparatus as an insulation and arc-quenching medium. However, the application of SF 6 gas faces two serious problems, including the heavy global warming effect and high toxicity of its decomposition products. So, scholars committed to finding environmental-friendly alternative to SF 6 gas and the relevant research results have been obtained.

    May 30, 2014While plasmas using mixtures of SF 6, C 4 F 8, and Ar are widely used in deep silicon etching, very few studies have linked the discharge parameters to etching results. The authors form such linkages in this report. The authors measured the optical emission intensities of lines from Ar, F, S, SF x, CF 2, C 2, C 3, and CS as a function of the percentage C 4 F 8 in the gas flow, the total gas
