• 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

    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.

    Abstract. Sulfur hexafluoride (sf6 gas) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, sf 6 emissions from China were inventoried for 1990-2010 and projected to 2020. Results reveal that the highest insulating gas emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the Sulfr hexafluoride production sector (each about 10%).
