Abstract
Electrical conductivity of 50Li₂O-xTiO₂-(50-x)P₂O5 glasses has been studied with an increase of the intermediate TiO₂ content. Thermal properties were observed from TG-DTA measurement and the variation of glass structure was investigated by FT-IR. The density and glass transition temperature increased with an increase of the TiO₂ content. These results were attributed to the fact that bond strengthening was occurred because of the formation of P-O-Ti cross linkages in the glass. The ionic conductivity increased with TiO₂ content and a maximum value, 1.2×10-6S/cm showed at x=20. The Ionic conductivity showed a large increasement as a result that the pyrophosphate group become the predominant structural unit. This result can explain that Li ions mobility increased as a number of non-bridging oxygen on phosphate units increased.
