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.orgChemical formula: SF₆Molar mass: 146.06 g/molMelting point: −64 &C; −83 &F; 209 KSolubility in water: 0.003% (25 &C)RAIL INCIDENT REPORT dpti.sa.gov.au/__data/assets/pdf_file/0009/287298/Rail...PDF fileCircuit Breaker Failure, Lonsdale 28th April 2016 Summary of the Report At 6:53 hrs on 28th April 2016 an incoming 66kV gas insulated circuit breaker (CB1081) at the Rail Feeder Station (RFS) experienced an internal short circuit resulting in ionisation of the gas
