    Abstract. 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 productionCited by: 93

    Model calculations using estimated reaction rates of sulfur hexafluoride (SF 6) with OH and O(1 D) indicate that the atmospheric lifetime due to these processes may be very long (25,000 years).An upper limit for the UV cross section would suggest a photolysis lifetime much longer than 1000 years.

  • Hexafluorophosphate - Wikipedia

    Hexafluorophosphate is an anion with chemical formula of PF − 6.It is an octahedral species. It imparts no color to its salts. PF − 6 is isoelectronic with sulfur hexafluoride, SF 6, and the hexafluorosilicate dianion, SiF 2− 6, and fluoroantimonate SbF − 6.Being poorly nucleophilic, hexafluorophosphate is classified as a non-coordinating anion.
