Sulfur Hexafluoride (SF6) Emission Estimates for China: An

Sulfur hexafluoride (SF6) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, SF6 emissions from China were inventoried for 1990–2010 and projected to 2020. Results reveal that the highest SF6 emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector

Sulfur Hexafluoride - an overview | ScienceDirect Topics

Sulfur hexafluoride is an inert perfluorine, routinely detectable in sea water at ∼0.01 fmol kg −1 by electron-capture gas chromatography (1 fmol=10 −15 mol). At room temperature and pressure SF 6 is a gas, but it forms a dense (ρ=1880 kg m −3) liquid at pressures exceeding 20 bar. It is extremely stable in the environment and, other
