  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made and naturally occuring 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.

    Germany. Over the same period the use of SF6 as cover gas dropped from 6.1 to 3.0 t. As prescribed by the IPCC guidelines, our study assumed that consumption of SF6 for magnesium casting equates with SF6 emissions from this sector. Hence, emissions also dropped by half from 1995 to 1997. For 1998, SF6 emissions were estimated to be 3.1 t.
