  • Theoretical study of the decomposition mechanism of SF6/Cu

    Sep 10, 2018Among all the decomposition pathways, the favorable decomposition reactions of SF 6 + Cu mixtures are found: reaction R1 contributes more than reaction R2 in the decomposition of SF 6 + Cu mixtures due to its lower energy released; reaction R3 is dominant in the decomposition of SF 5 + Cu other than multi-step reactions; the chemical processes of SF 4 + Cu → IM x → TS y (where x stands for 9, 10 and 13, and y denotes 7, 8 and 9) may play the same role in SF 4 + Cu decomposition,
