Theoretical analysis for ultrasonic properties of vanadate glasses over a wide range of composition

The various ultrasonic properties of PbO-V2O5, MoO3-PbO-V2O5, P2O5-V2O5, and CuO-P2O5-V2O5 and TeO2-K2O-V2O5 glass systems were analyzed and predicted over a wide range of composition. The theoretical elastic moduli and Poisson's ratio were evaluated on the basis of Makishima-Mackenzie's theory and Rocherulle et al. model and compared with the corresponding experimental ones. The composition dependence of ultrasonic attenuation coefficient in PbO-V2O5 glasses has also been analyzed and predicted, for the first time, using Abd El-Moneim's semi-empirical formula, which correlates the room temperature ultrasonic attenuation coefficient with the packing density, dissociation energy per unit volume and average first-order stretching force constant. The results revealed that:
