Correlation between mechanical, gamma shielding features and tellurium oxide concentrations in molybdenum aluminum strontium borate glass

This study investigates the effect of adding TeO₂ instead of B₂O₃ in a glass system containing a fixed amount of Al₂O₃, MoO₃, and SrO as modifiers. The present work included the impact of the addition of TeO₂ on radiation and mechanical properties theoretically. The shielding properties were calculated based on XCOM data, and mechanical properties were computed based Makishima-Mackenzie's model. The addition of TeO₂ reduced the packing density gradually. Besides, Young's longitudinal, shear, and bulk moduli showed the same behavior. In contrast, the density and shielding properties enhanced progressively with increasing TeO₂ instead B₂O₃, like mass attenuation coefficient, transmission factor, effective atomic number, radiation protection efficiency, charged particle range, etc. It can be concluded that adding TeO₂ reduced the glass elasticity and enhanced radiation shielding features, leading to potential utilization in the gamma and charged particle shielding scope.
