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

    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
