  • 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

    Sulfur hexafluoride (SF 6) gas has been used in large-scale electrical equipment, because of its excellent high-voltage dielectric strength. However, SF 6 has been identified as a greenhouse gas, because of its high global warming potential (GWP) and extended lifetime in the atmosphere. Based on theoretical calculations, trifluoromethanesulfonyl fluoride (CF 3 SO 2 F) is a relatively eco-friendly gas with a lower GWP than that of SF 6, and the electrical performance of CF 3 SO 2 F is also

    Sulphur hexafluoride (SF 6) is a synthetic (i.e., human-made) gas that is colourless, odorless, non-toxic (except when exposed to extreme temperatures), and non-flammable. It is heavier than air and hence stays close to the ground upon release which can cause death by suffocation if large quantities are involved.
