  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent man-made 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 de

    IDENTIFICATION: Sulfur hexafluoride is a colorless, odorless and tasteless gas. It can also be a liquid at extremely low temperatures. It is moderately soluble in water. It is a Greenhouse Gas which contributes to climate change. Sulfur hexafluoride is more effective at trapping heat than carbon dioxide. The Global Warming Potential of sulfur hexafluoride is quite high (25,000; the Global Warming Potential of CO2 is 1) and amongst the highest of all chemicals.
