Raman and crystallization behaviors of TeO2–Sb2O4 glasses

Transparent glasses obtained in the TeO2–Sb2O4 system have been investigated by Raman spectroscopy and differential scanning calorimetry. The glass transition temperature evolution registered in function of the composition was correlated to the structural modification of the glass network. Temperature programmed X-ray diffraction allowed the identification of the different phases that appear during the crystallization of these glasses. A correlation between the structure of the initial crystalline phase and the local structure of the glass was discussed.
