ELECTRICAL-CONDUCTIVITY IN SF6 THERMAL PLASMA AT LOW-TEMPERATURE (1000-5000 K)

The calculation of the electrical conductivity of SF6 thermal plasma h as been performed including the contribution of the ionic current, con sidering molecular ions and using a rather strong F-F- charge transfer interaction. The comparison between the new values and the previews o nes, in the temperature range 1000-5000 K and for pressures in the ran ge 0.1-1.6 MPa, shows that there is an important difference in particu lar under 2500 K. The increase of F-F- interaction has a very weak inf luence on the calculation of the electrical conductivity but the role of the electron-molecule interaction is important at low temperature. New values are given which allow one to complete the database of SF6's properties.
