where can I get buy small amount sulfur hexafluoride Vietnam

Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (sf6 gas) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on insulating gas in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to-date. Over a 100-year period, Sulfr hexafluoride is 22,800 times more effective at trapping infrared radiatioSee more on epa.govSulfur hexafluoride - Wikipedia en.wikipedia.org/wiki/Sulfur_hexafluorideSynthesis 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)Purchase gaz sf6 Gas from Concorde Specialty Gases | Concorde concordegas/purchase-sf6-gasPurchase Sulfr hexafluoride Gas.
