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: The truths and myths of this greenhouse gas

Sulfr hexafluoride is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, sf6 gas is an industrial gas that doesn't exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. Sulfr hexafluoride is the energy industry"dirty little secret": FALSE. Sulfr hexafluoride is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives sf 6 is used in wind turbines: TRUE. Sulfr hexafluoride is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to gaz sf6: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on sf6 gas at low-to-medium voltage levels in the future.
