The effect of PbO addition with different concentrations on four synthesized zinc titanium borate glasses with the chemical formula xPbO-(75-x) BO-10ZnO-10BaO-5TiO (x = 30, 35, 40, and 45 mol%) was explored in this study. The partial PbO substitution for BO increases the fabricated glasses' density by ≈ 20% from 5.31 to 6.37 g/cm, respectively, with raising the PbO concentrations between 30 and 45 mol.%, respectively. Besides, the substitution mentioned above enhances the gamma-ray attenuation properties where the linear attenuation coefficient increased between 69.911 and 102.245 cm (at 0.033 MeV), 0.341–0.415 cm (at 1 MeV), and 0.200–0.262 cm (at 10 MeV), increasing the PbO concentration between 30 and 45 mol.%, respectively. Simultaneously, increases in the PbO concentration within the fabricated glasses decrease the lead's equivalent thickness between 3.82 and 2.61 cm (at 0.033 MeV), 2.35–1.93 cm (at 1 MeV), and 2.81–2.14 cm (at 10 MeV). In contrast, substituting PbO for BO compounds diminishes the fabricated glasses' mechanical properties, where the microhardness decreased by 13.5 % from 4.24 to 3.67 GPa. The lead equivalent thickness (D) values at 0.66 MeV were found equal to 2.410, 2.232, 2.078, and 1.945 cm, and at 1.112 MeV, these values were found equal to 2.222, 2.081, 1.956, and 1.829 cm for G1, G2, G3, and G4, respectively.

掺杂 PbO 的 B2O3-ZnO-BaO-TiO2 玻璃的机械和伽马射线衰减特性的详细研究

研究了不同浓度的 PbO 添加对化学式为 xPbO-(75-x) BO-10ZnO-10BaO-5TiO (x = 30、35、40 和 45 mol%) 的四种合成的锌钛硼酸盐玻璃的影响。这项研究。 PbO 部分替代 BO 使制造的玻璃密度分别增加约 20%，从 5.31 g/cm3 增加到 6.37 g/cm3，同时 PbO 浓度分别提高 30 mol.% 和 45 mol.% 之间。此外，上述替代增强了伽马射线衰减特性，线性衰减系数在69.911至102.245 cm（0.033 MeV）、0.341-0.415 cm（1 MeV）和0.200-0.262 cm（10 MeV）之间增加，PbO 浓度分别增加 30 至 45 mol.%。同时，所制造的玻璃中 PbO 浓度的增加使铅的等效厚度降低到 3.82 至 2.61 cm（0.033 MeV 时）、2.35–1.93 cm（1 MeV 时）和 2.81–2.14 cm（10 MeV 时）。相比之下，用 PbO 代替 BO 化合物会降低制造的玻璃的机械性能，显微硬度从 4.24 GPa 下降到 3.67 GPa，降低了 13.5%。 0.66 MeV 下的铅当量厚度 (D) 值等于 2.410、2.232、2.078 和 1.945 cm，而在 1.112 MeV 下，G1、G2 的这些值等于 2.222、2.081、1.956 和 1.829 cm。分别是G3和G4。
