    Feb 01, 2020 · Sulfur hexafluoride (SF 6) is widely employed as an insulating medium in gas-insulated switchgear (GIS) because of its outstanding insulating and arc-extinguishing performance [, , , , ]. When power equipment works under normal conditions, SF 6 is quite stable; however, partial discharges (PDs) caused by GIS insulation defects can lead to SF 6 decomposing into some low-fluorine sulfides [ [6] , [7] , [8] ].

  • Sulfur hexafluoride - Wikipedia

    Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S 2 F 10 (which is highly toxic) and then scrubbing the product with NaOH to destroy remaining SF 4. Alternatively, utilizing bromine, sulfur hexafluoride can be synthesized from SF 4 and CoF 3 at lower temperatures (e.g. 100 °C), as follows:

    Sulfur hexafluoride (SFd)-contained gas is a common pollutant emitted during the etching process used in the semiconductor industry. This study demonstrated the application of radio-frequency (RF) plasma in the decomposition of SF6. The decomposition fraction of SF6 [etaSF6 (C (in)-C (out))/C (in) x 100%] and the mole fraction profile of the products were investigated as functions of input power and feed O2/SF6 ratio in an SiO2 reactor.
