Polyanion Effect at its Manifestation in Pure Form
A comparative analysis of polyanion effect is carried out at its manifestation in the pure form, i. e. with participation in process of electromigration only galogenidions, with polyalkali effect. It is shown that the expressions used for calculation of electric conductivity of two-alkaline glasses cannot be directly applied to the calculation of electric conductivity of two-galogenid glasses. Analytical expressions for such a calculation giving satisfactory compliance of the calculated and experimental data are offered.
