Abstract

Correlation between acoustical and compositional properties of TiO₂-Na₂O-CaO-P₂O₅, ZnO-PbO-B₂O₃, Bi₂O₃-V₂O₅-TeO₂, PbO-V₂O₅-TeO₂ and BaO-TeO₂ glass systems has been demonstrated to predict changes in ultrasonic attenuation coefficient and bulk modulus of these glasses. The correlation is based on the recently presented semi-empirical formula of Abd El-Moneim, which correlate the ultrasonic attenuation coefficient at room temperature with packing density, dissociation energy per unit volume and first-order stretching force constant of the glass. In addition, the theoretical values of bulk modulus were evaluated, using Makishima and Mackenzie theory, and compared with the observed values. It has been found that Abd El-Moneim semi-empirical formula as well as Makishima and Mackenzie theory can be applied successfully to predict changes in both ultrasonic attenuation coefficient and bulk modulus if the effect of the basic structural units that are present in the glass network is taken into account.

Key words: Glass, mechanical property, elastic modulus, microstructure, ultrasonic attenuation.
