Enhancement the Structural, Mechanical and Radiation Shielding of Borosilicate Glasses Doped Vanadium Ions

The structural, physical, mechanical, and radiation shielding characteristics of the glass system consisting of 27SiO 2 -53B 2 O 3 - 2ZnF 2 - ( 18-x ) Li 2 O- x V 2 O 5 ( 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 V 2 O 5 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 m 3 mol −1 to 15.36 × 10 –6 m 3 mol −1 . With the addition of V 2 O 5 , ultrasonic velocities, elastic moduli (experimentally and theoretically), hardness ( H ), and Debye temperature ( 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 V 2 O 5 content increases and the Li 2 O 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.
