Decomposition of sf6 gas in an RF Plasma Environment

Decomposition of SF 6 A sensitivity analysis of an earlier model showed that the applied power was the most important parameter and positively affects the decomposition fraction of re-actants in an RF plasma reactor.13 Figure 2 shows that when no oxygen was added to the reactor (feed O 2 /SF 6 ratio = 0.0), η gaz sf6 clearly increased from 37.79Get price

insulating gas Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of Sulfr hexafluoride as an insulating gas has led to many studies on insulating gas decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, sf6 gas decomposes to a wide variety of chemically active products which possess completely different properties from sf6 gas.Get price
