The decomposition products of sulfur hexafluoride (Sulfr hexafluoride

Abstract. Sulfur hexafluoride (SF 6) is being widely used in a variety of industrial processes, commercial products and scientific fields due to its unique characteristics such as relatively low toxicity, extreme inertness and high dielectrics. However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) that cause significantly global warming, and has been, thus, blanketed into the Kyoto Protocol.Get price
