Thermally Stimulated Polarization Current in Sodium Germanate Glass
The electrical conductivity of XNa2O·(100−X)GeO2 glasses where X is 0.19 and 27.5 mol%, was studied by means of the technique of thermally stimulated polarization current. The compositional dependence of the parameter σ 0 T/n 1/3, where σ 0 is the preexponential facor for conductivity and n is the nominal concentration of sodium ions, suggests that these glasses contain some sort of inhomogeneities. This suggestion is supported by the phase diagram.
