Raman Spectroscopic and DTA Studies of TeO₂-ZnO-Na₂O Tellurite Glasses

Abstract:

The ternary tellurite glass structure (TeO2-ZnO-Na2O) was analysed using the Raman spectroscopy in the range of 300-1000 cm-1. The influence of the concentration of alkali ion oxide on the structural change of tellurite glasses was discussed. It is evident that the network of structural units changes significantly with TeO2:Na2O ratio, which then influences the glass thermal properties. Glass density, molar volume, glass transition temperature, crystallization temperature and viscosity have been measured and calculated. These results provide clear evidence and explanation of the glass structural change.
