    The tracers used were Rhodamine-WT, sulfur hexafluoride, and a mixture of sulfur hexafluoride and neon-22. The tracers were injected into Herman Pit, a generally well-mixed water body of approximately 81,000 m2, and the concentrations were monitored in the mine pit, observation wells, and the lake for 2-3 months following each injection.

  • SF6 Gas Use in Electrical Applications - Sulphur Hexafluoride

    Sep 03, 2018Sulphur hexafluoride (SF 6) is a man-made gas comprising of one sulphur and six fluoride atoms.SF 6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and

  • Sulphur hexafluoride - Registration Dossier - ECHA

    Hydrolysis of sulphur hexafluoride is unlikely to occur as it contains no hydrolysable functional groups in its chemical structure. The atmospheric lifetime of SF6 was estimated by Ravishankara et al. (1993). The reaction of SF6 with O(1D) and the photolysis mediated by Lyman radiation were considered as the possible degradation pathways.

  • A Method to Convert Isotopically Modified Sulfur

    Dec 14, 2020A method has been proposed to convert isotopically modified sulfur hexafluoride to elemental sulfur by the reaction of sulfur hexafluoride with hydrogen in a high-frequency discharge: SF6 + 3H2 = S + 6HF. The optimal process conditions (the ratio between the reactants, the pressure in the reactor, the flow rate of the reaction mixture, and the yield of the desired products) are determined.
