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

Decomposition of sf 6 in an RF Plasma Environment

Sulfr hexafluoride clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η sf6 gas exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η gaz sf6 was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W). The addition of oxygen to the reactor re-Get price
