  • The decomposition products of sulfur hexafluoride (SF6

    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 fully
