Abstract
The consistent electron transport coefficients, for not only pure atoms and molecules but also binary gas mixtures, are necessary to quantitatively understand plasma phenomena and ionized gases. Electron transport coefficients in CF3I-N2 mixture gas, therefore, were calculated and analyzed using a two-term approximation of the Boltzmann equation in the E/N range (ratio of the electric field E to the neutral number density N) of 10 - 1000 Td (1 Td = 10− 17 V.cm2) for the first time. These coefficients include electron drift velocity, density-normalized longitudinal diffusion and density-normalized effective ionization coefficients. The present results were in good agreement with the available experimental data over a wide range of E/N. The limiting field strength value of E/N for 70% CF3I-N2 mixture was derived and greater than that of the pure SF6 gas. Gas mixtures of 65 – 75% CF3I-N2 could be considered to use in high voltage and many industries.
