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

A rapid method for the measurement of sulfur hexafluoride

Abstract. A rapid headspace method for the simultaneous laboratory determination of intentionally introduced hydrologic tracers, sulfur hexafluoride (SF 6 ), trifluoromethyl sulfur pentafluoride (SF 5 CF 3 ), Halon 1211 (CF 2 ClBr), and other halocarbons in water and gases is described. The high sensitivity of the procedure allows for introduction of minimal tracer mass (a few grams) into hydrologic systems with a large dynamic range of analytical detection (dilutions to 1:10 8 ).Get price
