This study investigates the effect of replacing B2O3 with TeO2 in a glass system containing a fixed amount of Al2O3, MoO3, and SrO. The impact of adding TeO2 on radiation and mechanical properties was theoretically analyzed. The addition of TeO2 gradually reduced the packing density and the Young's longitudinal, shear, and bulk moduli. However, the density and shielding properties, such as mass attenuation coefficient, transmission factor, effective atomic number, radiation protection efficiency, charged particle range, etc., enhanced progressively with increasing TeO2 instead of B2O3. It can be concluded that adding TeO2 reduced the glass elasticity and enhanced radiation shielding features, suggesting potential applications in the gamma and charged particle shielding scope.
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.
