Abstract
Dielectric constant epsilon', loss tan delta and ac conductivity sigma of Z nF2-Bi2O3-TeO2 glasses with varying concentrations of Bi2O3 (from 5 to 20%) are studied as a function of frequency and temperature over moderately wid e ranges. The dielectric breakdown strength for these glasses is also deter mined in air medium. From the analysis of these studies along with the IR s pectra & DTA recordings of these glasses, the structural changes in ZnF2-Bi 2O3-TeO2 glass system with change in the concentration of Bi2O3, are discus sed.
