sf6 Alternatives environmental impact monitor Electrical industry
sf6 Alternatives environmental impact monitor Electrical industrySulfur hexafluoride ( SF6) is colorless, odorless, heavier than air and is not considered as toxic. However it is suffocating at high concentrations (it replaces oxygen) just like inert gases (also called noble gases). Sulfur hexafluoride has no lower and upper explosive limits but can severely react with disilane and form a dangerous explosive

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)Storage and Handling of Gas Cylinders Guidelines documents.uow.edu.au/content/groups/public/
