DSC and DC Conductivity of Bi 2 O 3 · LiF · B 2 O 3 Glasses

Abstract

Fluoroborate glasses with Bi 2 O 3 content and having compositions x Bi 2 O 3 · ( 40 - x )LiF · 60B 2 O 3 ( x = 0, 5, 10, 15, and 20) are prepared using melt-quench technique. DSC characterization is carried out to observe glass transition temperature. Two such temperatures are observed for each of the reported samples. DC conductivity of the reported samples is studied with the variation in temperature from 313 K to 413 K by dividing this range into three regions, namely, low-, intermediate-, and high-temperature regions. DC conductivity responses for these temperature regions are explained using different conductivity models.
