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 ...

In order to combat the potential global warming effects of F-gases, and as part of the EU's Kyoto protocol commitments, in 2006 the European Union passed two pieces of legislation controlling their use: the F-gas Regulation (EC) No 842/2006 and the Mobile Air Conditioning Directive Directive 2006/40/EC. The F-gas Regulation adopts an approach ...
Conversely, an unnaturally low voice may be achieved by asking the singer to inhale sulfur hexafluoride. This technique is less popular than helium inhalation, in part because of the inherent risk of the gas displacing oxygen in the lungs. [4] [failed verification]
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 ...
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.
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 .
