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 scrubbing the product with NaOH …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:BrandMust include:BrandExplore furtherSulfur hexafluoride Uses, Side Effects Warnings DrugsdrugsSF6: The Little Gas That Could… Make Global Warming WorseforbesSulfur hexafluoride | F6S PubChempubchem.ncbi.nlm.nih.govAmazon: sulfur hexafluorideamazonSulfur Hexafluoride, the Anti HeliumthoughtcoRecommended to you based on what's popular • FeedbackProducts Search | Solvay solvay/en/search?f=fsection:ProductsSulfur Hexafluoride (SF6) is a non toxic, inert, insulating and cooling gas of high dielectric strength and thermal stability.

The surrounding air and the dielectric material in the vicinity of the cut high voltage cable screen become overstressed and breakdown of the HV cable will soon occur. To avoid this, equipotential lines are controlled by installing a HV cable termination with a stress cone, a HV cable termination with linear stress relief or a separable connector at the end of the cable screen.
