Abstract

The variation of some physical properties of equimolar copper-phosphate glasses has been reported in the literature. The present work studied a 60 mol% P2O5-40 mol % CuO glass system using electrical conductivity, infrared absorption, optical absorption spectroscopy and differential scanning calorimetry. The results revealed an increase in the activation energy and the optical energy gap compared with that for equimolar P2O5-CuO, which could be attributed to the variation of reduced valence states of the copper ion in the process of glass formation. The relation between the a.c. electrical conductivity with frequency was found to be almost temperature-independent. Infrared measurement revealed similar trends to those reported for the same glass composition. DSC measurements showed endothermal peaks at 360, 520, 560 and 580 °C for this glass composition.
