The article presents the comparative analysis of the polyanion effect at its manifestation in the pure form, i.e. with the participation in the electromigration process of only halide-ions with the polyalkali effect. It was shown that expressions used to calculate the electrical conductivity of two-alkali glasses, can not be directly applied to calculate the electrical conductivity of two-halide glasses. Analytical expressions for such calculation are proposed, giving a satisfactory compliance of calculated and experimental data.

Keywords: polyanion effect, polyalkali effect, electrical conductivity, transfer numbers, nature of conductivity, additivity of electrical conductivity
