SF6 gas Mixtures Decomposition for subway. PD can cause decomposition of sf 6 gas, resulting in the production of various low-fluorine sulfides, such as SF 4, SF 3, SF 2, and S 2 F 10. 1 – 3 Because of the presence of trace impurities, such as H 2 O and O 2, in the equipment, these low-fluorine sulfides generate many more stable decomposition products, such as SOF 2, SO 2 F 2, SO 2
