  • Chemical Decomposition of High Pressure SF6/N2 (5:95

    Abstract. Sulfur hexafluoride (SF 6) is the insulator gas used in most of equipments handling high and very high voltages.Owing to its high global warming potential, SF 6 has been classified during the Kyoto conference on climate change among the greenhouse gases. Its emission in the atmosphere must therefore be reduced 1.In order to comply with this aim, one of the solutions adopted by theCited by: 1
