Diffusion of potassium ions and electrical conductivity in glass for electronic optics

Abstract

The results of a study of the electrical conductivity and diffusion of potassium ions in borate-barium glass (C78–5) – 2,2% SiO2 57,8% B2O3 8,2% K2O 19,0% BaO 3,5% CaO 8,8% Al2O3 0,5% MgO with the passage of electric current through the sample. The time dependences of self-diffusion coefficients are calculated for the transmission of an electric current at a constant temperature.
