Collisional Decomposition of Sulfr hexafluoride | NIST

Sep 01, 2000 · Abstract. Insulating gas mixtures containing SF 6 have been promoted to serve as replacements for pure SF 6 in order to reduce SF 6 atmospheric emission. It has been argued that some synergism may be achieved by choosing proper buffer gases in mixtures with SF 6 such that the buffer gases efficiently slow down electrons into an energy range where the electron attachment cross section for SF 6 is large.Get price

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
