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)Missing:Pressure gaugeMust include:Pressure gaugePeople also askWhat is the pressure of compressed sulfur hexafluoride?What is the pressure of compressed sulfur hexafluoride?Since leakage of the gas is a possibility, the pressure will in practice may be less than 5 atm. The dielectric performance of the bushings is a function of the pressure of the SF 6 The U.S. Navy is interested in evaluating the dielectric performance of SF 6Breakdown Voltage of Compressed Sulfur Hexafluoride (SF6
