摘要

The intrinsic aim of this work is to understand the influence of composition change on the physical-electrical parameters of glasses with the composition (20-Y) Li2O-YAg2O–20MgO–10Bi2O3-50SiO2 (Y = 0.25, 0.5, 1.0, 2.0 and 4.0 mol%). The results of the physical parameters indicate a growth in the strength of the glass structure with the increase replacement of Li2O by Ag2O. However, the decrease in loss factor ε″, and AC conductivity σac of glasses may be attributed to the decrease in the space charge polarization (scp). AC conductivities exhibit simple power law variation. The s values essentially lie in the range of 0.67–0.92, which is typical of conductors in Jonscher regime. Dielectric properties (constant ε′, loss ε″ and ac conductivity σac, over a range of frequency 100–100 kHz and temperature RT (Room Temperature)–200 °C and frequency exponent s) of these glasses have been studied The results indicate a great potential of the prepared glasses as promising materials that can be used for solid state electrolytes.
