• Sulfur hexafluoride - Wikipedia

    OverviewSynthesis and reactionsApplicationsGreenhouse gasPhysiological effects and precautionsSulfur 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

  • Efficient Removal of Sulfur Hexafluoride (sf6 gas) Through

    Abstract This paper reports that recycled electroplating sludge is able to efficiently remove greenhouse gas sulfur hexafluoride (SF 6). The removal process involves various reactions of SF 6 with the recycled sludge. Remarkably, the sludge completely removed SF 6 at a capacity of 1.10 mmol/g (SF 6 /sludge) at 600 °C.
