The goal of the present paper is to complete our very recent work [J. Fluor. Chem. 210 (2018) 156–165] on the quantitative analysis and prediction of elastic properties, ultrasonic attenuation coefficient and glass transition temperature in binary BaF₂-TeO₂ glass system over the composition range 7 mol % ≤BaF₂ ≥19 mol %. All the above mentioned parameters were correlated with the ratio between packing density and mean atomic volume of the glass on the basis of Abd El-Moneim and Alfifi’s approaches [2018]. In addition to this, the theoretical elastic moduli and Poisson’s ratio were evaluated on the basis of the Rocherulle et al. model [1989] and compared with the corresponding experimental ones. The results show that, the ratio between packing density and mean atomic volume can be considered as a new powerful tool capable of predicting changes in ultrasonic attenuation coefficient, elastic properties and glass transition temperature. Although both the theoretical and experimental elastic moduli display the same compositional trend; a slight discrepancy between the theoretical and experimental values of shear, longitudinal and Young's moduli is observed. This discrepancy has been attributed to the anomalous behavior between various elastic properties and calculated dissociation energy per unit volume. Finally, not only Rocherulle et al. model [1989] is valid for majority of the investigated glasses, but also the correlation ratios between theoretical and experimental elastic moduli are better than those reported previously when compared the same experimental elastic moduli with the theoretically calculated ones on the basis of Makishima-Mackenzie’s theory [1973, 1975].

本文的目标是完成我们最近的工作[J. 氟。化学 210（2018）156-165]的定量分析和弹性性能，以二进制的BaF超声衰减系数和玻璃化转变温度的预测₂ -TeO _2个以上的组成范围7摩尔％≤BaF玻璃系统₂≥19摩尔％。根据Abd El-Moneim和Alfifi的方法[2018]，上述所有参数均与玻璃的堆积密度与平均原子体积之比相关。除此之外，在Rocherulle等人的基础上评估了理论弹性模量和泊松比。模型[1989]并与相应的实验模型进行比较。结果表明，堆积密度与平均原子体积之比可以被认为是一种能够预测超声衰减系数，弹性和玻璃化转变温度变化的强大工具。尽管理论上和实验上的弹性模量都显示出相同的组成趋势；剪切，纵向和杨氏的理论值和实验值之间略有差异 观察到s模量。该差异归因于各种弹性特性与计算出的每单位体积的离解能之间的异常行为。最后，不仅Rocherulle等人。模型[1989]对于大多数被研究的眼镜都是有效的，但是当根据Makishima-Mackenzie理论将相同的实验弹性模量与理论计算的弹性模量进行比较时，理论和实验弹性模量之间的相关比也比先前报道的要好。 [1973，1975]。
