Sulfur hexafluoride or sulphur hexafluoride (British spelling) is an inorganic compound with the formula SF 6. It is a colorless, odorless, non-flammable, and non-toxic gas. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. [citation needed] Typical for a nonpolar ...

Sulphur hexafluoride (SF 6) is used primarily as an arc suppression and insulation gas. It can be found in high-voltage switchgear and is used in the production of magnesium. Nitrogen trifluoride (NF 3) is used primarily as an etchant for microelectronics fabrication.
Some manufacturers also offer sulfur hexafluoride as an insulating gas, particularly as sound proofing. It has only 2/3 the conductivity of argon, but is stable, inexpensive, and dense. However, sulfur hexafluoride is an extremely potent greenhouse gas. In Europe, SF
Addition of sulfur hexafluoride can dramatically improve the dielectric properties of poorer insulators, e.g. helium or nitrogen. [2] Multicomponent gas mixtures can offer superior dielectric properties; the optimum mixtures combine the electron attaching gases ( sulfur hexafluoride , octafluorocyclobutane ) with molecules capable of ...
Lower-period elements, however, may form hypervalent molecules, such as phosphorus pentafluoride or sulfur hexafluoride. [78] The reactivity of such species varies greatly—sulfur hexafluoride is inert, while chlorine trifluoride is extremely reactive—but there are some trends based on periodic table locations. Boron trifluoride is a planar ...
A hexafluoride is a chemical compound with the general formula QX n F 6, QX n F 6 m−, or QX n F 6 m+. Many molecules fit this formula. Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid (H 2 SiF 6 ), which is a byproduct of the mining of phosphate rock .
Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6 ) gas to cool and quench the arc on opening a circuit.
