Abstract

We investigated DC conductivity in 60V2O5–(40-x) P2O5–x B2O3 glasses as a function of temperature. The measurements were carried out in a temperature range of 302–473 K. For all compositions, the DC conductivity increased with the increasing B2O3. The increase in conductivity was more pronounced due increased in number of non-bridging oxygens (NBOs). The maximum value of conductivity was found to be 9.8510−4 Scm−1 at 473 K for 35 mol % of B2O3. Tg and Tc was found to be 110 ºC and 140 ºC respectively for 35 mol % of B2O3. The ionic conductivity was found to be dominant over the electronic conductivity..
