Abstract

A method to calculate the dielectric strength (DS) for SF ₆/CF₄ mixtures of various ratios was proposed. The cross sections of relevant electron-molecule processes in Cf₄ and SF ₆ were scaled to stimulate DS, electron drift velocities , and attachment and ionization coefficients. The possible variations of the differences of the rate constants between the mixture and the pure gas and observed the qualitative stability. It was found that the asymmetric location of the mixture content vs DS maximum was related to the increased SF₆ ionization and also to suppressed CF₄ ionization.
