The effects of a thermal treatment at a temperature Tina = 50�C for a series of binary V2O5- GeO2 glasses fused and equilibrated at various temperatures (T) in air were measured. T ranged from 1000�C to 1350�C. During the heat treatment microstructural changes and increase in electrical conductivity of these glasses as measured by infra-red spectroscopy and electrical studies revealed that these changes with thermal treatment at 350�C also depend upon T. This behaviour as well as the T?dependent changes in properties as previously reported supports the conclusion that the structure of these glasses depend upon the temperature at which the glass was fused and equilibrated. � 1987 Elsevier Science Publishers B.V.
