摘要

The structural, physical, mechanical, and radiation shielding characteristics of the glass system consisting of 27SiO2-53B2O3- 2ZnF2- (18-x) Li2O-xV2O5 (0 ≤ x ≤ 2) were studied. The glasses were fabricated using the melt-quench method. It was found that the density and molar volume of the current glasses were influenced by the V2O5 content. The structural characteristics were investigated using X-ray diffraction (XRD). Using the pulse-echo method, longitudinal and shear velocities were measured to study elastic characteristics. The radiation shielding characteristics were determined using the Phy-X program for γ rays. The densities varied from 3090 kgm−3 to 4140 kgm−3, whereas molar volume varied from 19.6 × 10–6 m3 mol−1 to 15.36 × 10–6 m3 mol−1. With the addition of V2O5, ultrasonic velocities, elastic moduli (experimentally and theoretically), hardness (H), and Debye temperature ( \({\theta }_{D}\) θ D ) were increased. It is noteworthy that the theoretically predicted elastic moduli, obtained using the (MMM) model, exhibits a remarkable agreement with the experimentally determined elastic moduli. This consistency is further corroborated by the shielding properties of the borosilicate glasses. As the V2O5 content increases and the Li2O decreases, the MAC values increase suggesting greater radiation shielding capacities. It’s observed that the MAC values for G5 are higher than those for G1. Therefore, it is a great choice for application in the field of radiation shielding.
