    Jan 24, 2017 · According to an experimental study, S 2 F 10 and S 2 F 10 O are the unique decomposition components under spark discharge, and they cannot be detected under PD. Therefore, S 2 F 10 and S 2 F 10 O can be used as the characteristic gases of spark discharge. However, the decomposition components of SF 6 under PD mainly contain SOF 4, CF 4, SO 2 F 2, SOF 2, H 2 S, SO 2, and HF.
