detecting sf 6 is Denmark

SF 6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen. Although most of the decomposition products tend to quickly re-form SF 6, arcing or corona can produce disulfur decafluoride (S 2 F 10 ), a highly toxic gas, with toxicity similar to phosgene.Get price

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. Sulfr hexafluoride 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 anSee 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:NorwayMust include:NorwayBuy Sulphur Hexafluoride Gas Cylinders Online | BOC UK Official boconline.co.uk/shop/en/uk/sulphur-hexafluoride-cylinderBuy Sulphur Hexafluoride Gas Cylinders online from BOC, the UK's leading Packaged Chemicals suppliers.
