Abstract
In this work, the radiation shielding capacity of novel BaZrO3 perovskite-doped sodium borate glasses with compositions of 40Na2O–60B2O3+ x BaZrO3 (where x = 0, 10, 20, and 30% wt.) was examined. XRD and FTIR have been used to analyze the structural characteristics of the produced glass systems. The relative concentration of BO4 units in the sodium borate glass N4 decreased by adding 10% from BaZrO3 and then increased. Also, the optical energy increases from 3.2 eV to 3.34 eV as the BaZrO3 content reaches 10% and then drops to 3.15 eV with an increase in the BaZrO3 content to 30%. Further, glasses' electronic polarizability, reflection loss, and optical transmission were investigated. The gamma-radiation shielding characteristics of novel BaZrO3-based glasses were experimentally investigated. The MAC values enhanced from 0.0534 cm2/g for NB glass to 0.0685 cm2/g for NB+30% BaZrO3 at the energy of 1.333 MeV. Furthermore, the experimental and theoretical findings for mass attenuation coefficient (MAC) have also been compared utilizing Phy-X/PSD software. In addition, the exposure build-up factor (EBF), removal cross-sections of fast neutrons, and equivalent atomic numbers (Zeq) have been computed. According to the results, adding BaZrO3 perovskite seems to boost the gamma-ray shielding effectiveness of sodium borate glass.
