Measurement of transport properties of SF6 at high temperatures and pressures

摘要: The electrical and thermal conductivity the net radiation emission of a sulfur hexafluoride plasma were measured for temperatures up to 22 500 K at 1, 4 8 bar. These measurements made on wall stabilized cascade arcs 3 5 mm diameter using spectroscopy. was in fair agreement with theory but found be pressure dependent. k, 1 bar good other experimental results Frie Motschmann, higher by factor three as compared theoretical estimates Frost Liebermann. At values k six eight, respectively. high value attributed contribution thick absorption within arc column. have shown first time, strong dependence apparent conductivity. u also higher, two, Liebermann Lowke.
