Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Sulfur hexafluoride purification from mixtures with air: a

Using a molecular sieve concentration trap and previously developed laboratory electron capture chromatographic procedures, sulfur hexafluoride was determined from 40 cm/sup 3/ samples with levels as low as 0.03 x 10/sup -12/ cm/sup 3//cm/sup 3/ - more than an order of magnitude below the present tropospheric SF/sub 6/ concentration of 0.3 to 0.5 x 10/sup -12/ cm/sup 3//cm/sup 3/.Get price
