To investigate the effects of increasing the amount of BiO in the glass composition, a novel glass system was created with the following chemical composition: 5LiO-5BaO-10ZnO-(30-x) BO-(50+x) BiO. x = 10, 15, 20 mol%. A micro-Raman spectrometer (WITec alpha300 R) was utilized to demonstrate the change in chemical bonds brought on by the addition of BiO. Additionally, the Makishema-Makinze theory was employed to calculate the manufactured glasses' mechanical properties. According to the theoretical analysis of mechanical properties, switching from BO to the compound BiO results in a decrease in elastic moduli, packing density, and hardness. Additionally, the gamma-ray shielding properties were evaluated experimentally using a high purity germanium detector and affirmed using the Monte Carlo simulation. The analysis showed that raising the BiO content from 60 to 70 mol% resulted in a linear attenuation coefficient enhancment by 12.4% (at 0.059 MeV), 12% (at 0.662 MeV), and 10% (at 2.506 MeV).

Li2O-BaO-ZnO-B2O3-Bi2O3 玻璃体系的结构和辐射屏蔽特性的实验研究

为了研究增加玻璃成分中 Bi2O 含量的影响，创建了一种具有以下化学成分的新型玻璃系统：5LiO-5BaO-10ZnO-(30-x) BO-(50+x) BiO。 x = 10、15、20 摩尔%。利用微型拉曼光谱仪 (WITec alpha300 R) 来证明添加 Bi2O 所带来的化学键变化。此外，还采用 Makishema-Makinze 理论来计算制造的玻璃的机械性能。根据力学性能的理论分析，从BO转变为化合物Bi2O会导致弹性模量、堆积密度和硬度下降。此外，使用高纯度锗探测器对伽马射线屏蔽性能进行了实验评估，并使用蒙特卡罗模拟进行了确认。分析表明，将 Bi2O 含量从 60 mol% 提高到 70 mol% 会导致线性衰减系数提高 12.4%（0.059 MeV 时）、12%（0.662 MeV 时）和 10%（2.506 MeV 时）。
