Sulfur hexafluoride - Wikipedia hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an excellent 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.Chemical formula: SF₆[email protected]
