Synthesis and ReactionsApplicationsGreenhouse GasPhysiological Effects and PrecautionsSee AlsoFurther ReadingExternal LinksSulfur hexafluoride on Earth exists primarily as a man made industrial gas and has also been found to occur naturally. SF6 can be prepared from the elements through exposure of S8 to F2. This was also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901. Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S2F10 (which is highly toxic) and then scrub…See more on en.wikipedia.orgMissing:High qualityMust include:High qualitySynthesis and reactionsApplicationsGreenhouse gasSee alsoReferencesg3, the SF6 free solution in practice | Think Grid think grid.org/g3 sf6 free solution practice2019/2/18SF6 free solutions.
