Abstract
The dielectric constant and the electrical conductivity of the transparent glasses in the composition 3Na2O-7B2O3 (NBO) were investigated in the 100 Hz–10 MHz frequency range at various temperatures. The activation energy associated with the electrical relaxation determined from the electric modulus spectra was found to be 0.76 ± 0.02 eV, close to that (0.74 ± 0.02 eV) obtained from DC conductivity studies. The frequency-dependent electrical conductivity was analyzed using Jonscher’s power law. Temperature-dependent behavior of the frequency exponent (n) suggested that the correlated-barrier hopping model was the most appropriate to rationalize the electrical transport phenomenon in NBO glasses.
