Abstract
Regarding to a high-temperature CO2 added with CF3I, the present paper reports equilibrium compositions as one of fundamental properties. Firstly, 61 particles were taken into account and the equilibrium compositions were derived in a temperature range from 300 to 30,000 K. Secondly, the particles present after an arc interruption in the CO2-CF3I mixture are obtained as a function of CF3I concentration. Thirdly, the electron density of the CO2-CF3I mixture at high temperatures is discussed in comparison with that of pure CO2.
