Year: 2025
Type: article
Abstract: 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 σ ac 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.
