Material functions of sulphur hexafluoride

Several material functions of SF 6 were calculated for temperatures between 1000K and 20000K and for pressures of 0.1, 0.5, 1, 2.5, 5 and 10 MPa. In the basic equations for the computation of SF 6 material functions, the authors have also taken into account plasma nonideality effects. They have analysed the SF 6 plasma radiation in high current discharges using an Optical Multichannel Analyser, to determine the dependence on the current and the discharge pressure.
