A review on sf 6 substitute gases and research status of CF3I

Nov 01, 2018 · Yokomizu et al. from Nagoya University Japan investigated high-temperature plasma of CF 3 I/CO 2. They determined that the conductivity of CF 3 I/CO 2 increases with the increase of CF 3 I when the temperature is below 10 kK. Its thermal conductivity is related to CF 3 I when the temperature is approximately 7000 K.
