Effect of Na2O on Structural and Thermal Properties of Cadmium Borate Glasses
Na2O doped cadmium borate glasses were prepared by standard melt quench method with the composition 70B2O3-(30-x)CdO-xNa2O (where x=0, 5,10,15 and 20 mol %).The prepared glass samples are subjected to characterization such as XRD, SEM, FTIR and DTA techniques. XRD and SEM reveal the amorphous nature of the glass samples. Various band positions are confirmed by FTIR and the fraction of BO4 units increases at the expense of BO3 structural units with the increasing concentration of Na2O. The glass transition temperature (Tg), crystallization temperature (Tc) and melting temperature(Tm) are determined using DTA analysis. Thermal stability factor against devitrification is calculated using Tg, Tc and Tm values.
