The decomposition products of sulfur hexafluoride (Sulfr hexafluoride

From the environmental and health points of view, it is necessary to mitigate and control the emissions of the decomposition products from SF 6 destruction processes because most of them (e.g. S 2 F 10, SF 4 and HF) are highly reactive, corrosive and toxic, and few of them are also potent GHGs. This article aimed to introduce the fullyGet price

Decomposition of sf 6 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 Sulfr hexafluoride clearly increased from 37.79Get price
