Materials | Free Full-Text | Thermal Decomposition Properties

During heating from 200 °C to 650 °C, the five gases of CO 2, SO 2, H 2 S, SOF 2, and CF 4 are selected as the characteristic decomposition components of SF 6. CO 2, SO 2 and SOF 2 are all formed at 275 °C and the formation rate increases exponentially, but the formation rate of CO 2 gradually decreases after CF 4 has been generated.Get price
