  • Decomposition Characteristics of SF6 and Partial Discharge

    Pure SF6gas has stable chemical properties and is not easily decomposed. However, under the effect of the partial discharge (PD), spark discharge, arc discharge, overheating, and other factors, SF6gas is decomposed into various low-fluoride sulfides (such as SF5, SF4, SF3, SF2, and SF).

  • 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
