Abstract :
The transport of potassium ions through potassium borosilicate glass has been investigated experimentally by measuring the back side current induced by ion bombardment of the front side. The experimental data are compared to calculations employing the Nernst-Planck-Poisson model. The analysis allows deriving the bulk ion conductivity respectively diffusion coefficient of the material. The role of interface transport is discussed.
