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 ...
The other known sulfur fluorides are sulfur difluoride, sulfur tetrafluoride, sulfur hexafluoride, disulfur decafluoride, disulfur difluoride and thiothionyl fluoride, difluorotrisulfane, and difluorotetrasulfane. [10] The F top atom can be substituted with Cl to yield ClSSF 3 (2-chloro-1,1,1-trifluorodisulfane). [5]
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.
Sulfur hexafluoride is nearly inert and non-toxic due to steric hindrance (the six fluorine atoms are arranged so tightly around the sulfur atom that it is extremely difficult to attack the bonds between the fluorine and sulfur atoms). It has several applications due to its stability, dielectric properties, and high density.
Sulfuryl fluoride (also spelled sulphuryl fluoride) is an inorganic compound with the formula SO 2 F 2.It is an easily condensed gas and has properties more similar to sulfur hexafluoride than sulfuryl chloride, being resistant to hydrolysis even up to 150 °C. [3]
Disulfur decafluoride arises by the decomposition of sulfur hexafluoride. It is produced by the electrical decomposition of sulfur hexafluoride (SF 6)—an essentially inert insulator used in high voltage systems such as transmission lines, substations and switchgear. S 2 F 10 is also made during the production of SF 6.
Sulfur hexafluoride in an electric arc may also react with other materials and produce toxic compounds, e.g. beryllium fluoride from beryllium oxide ceramics. Frequently used in mixtures with e.g. nitrogen or air. Nitrogen: N 2: 1.15: 28: 1.251 – – not Often used at high pressure. Does not facilitate combustion.
