Abstract

• Borate glasses containing the network modifier oxide ZnO was prepared by melt quenching technique. The structural characterization of these glass samples has been investigated by using Xray powder diffraction technique (XRD). The morphology of these samples has been determined by using SEM. The transition temperature and crystallization temperature of these glasses were determined by TGA-DTA method. Thermal stability (∆T) of the glass samples with the different compositions was identified. The FTIR spectroscopy was also used to study the bonding structure of these glasses in the range from 400 to 4000 cm-1 . It was found that the Bi3+ cations were incorporated in the glass structure as BiO3 and BiO6 units and also boron ions were incorporated as BO3 and BO4 units.
