  • 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 of

  • Measurement of the diffusion coefficient of sulfur

    Abstract. Sulfur hexafluoride has been widely used in field studies and laboratory experiments to develop a relationship between gas transfer and wind speed. The interpretation of the data from such studies requires the diffusion coefficient of SF 6 ( Dsf 6 ), which has not previously been measured. In this study, DSulfr hexafluoride has been determined in pure water and in 35‰ NaCl over a temperature range of 5–25°C.

    Sulphur hexafluoride (SF 6) is a synthetic (i.e., human-made) gas that is colourless, odorless, non-toxic (except when exposed to extreme temperatures), and non-flammable. It is heavier than air and hence stays close to the ground upon release which can cause death by suffocation if large quantities are involved.
