Abstract

A novel series of borate-based glasses in the system (xGd₂O₃-52.5B₂O₃-17.5SiO₂-5TiO₂-(25-x) Na₂O: where x ranges from 0 to 12 mol%, were successfully synthesized and characterized. The density (ρ), of BSTNG-0 without Gd₂O₃ is 2.945 gcm⁻³, with the addition of Gd₂O₃ from 2 to 12 mol%, the (ρ), values of (BSTNG-2 – BSTNG-12) is between (3.318 and 4.882 gcm⁻³). X-ray diffraction configurations of BSTNG glasses revealed no indication of crystalline bands. It is noteworthy that the BSTNG-12 glass sample, with a value of approximately 101 °C, exhibits the strongest thermal stability against crystallization. As the insertion of Gd₂O₃ the (L, G, K, and Y GPa), values are described as:L increase from 75.3 for BSTNG-0 to 137.4 for BSTNG-12, G increase from 16.3 for BSTNG-0 to 31.45 for BSTNG-12, K increase from 53.48 for BSTNG-0 to 95.5 for BSTNG-12, Y increase from 44.5 for BSTNG-0 to 85.03 for BSTNG-12. Among all the prepared samples, BSTNG-12 demonstrated the most effective gamma radiation shielding performance, attributed to its higher density and enhanced structural compactness.

Gd2O3 - B2O3-SiO2-TiO2-Na2O玻璃的物理、结构、机械、热学和γ辐射屏蔽特性

在xGd2O3-52.5B2O3-17.5SiO2-5TiO2-(25-x) Na2O体系中成功合成了一系列硼酸盐基玻璃，其中x在0 ~ 12 mol%范围内。未添加Gd2O3的BSTNG-0的密度（ρ）为2.945 gcm−3，当Gd2O3添加量为2 ~ 12 mol%时，（BSTNG-2 - BSTNG-12）的ρ值在3.318 ~ 4.882 gcm−3之间。BSTNG玻璃的x射线衍射结构显示没有晶体带的迹象。值得注意的是，温度约为101℃的BSTNG-12玻璃样品具有最强的抗结晶热稳定性。随着Gd2O3的加入，（L、G、K和Y GPa）的取值为：L从BSTNG-0的75.3增加到BSTNG-12的137.4，G从BSTNG-0的16.3增加到BSTNG-12的31.45，K从BSTNG-0的53.48增加到BSTNG-12的95.5，Y从BSTNG-0的44.5增加到BSTNG-12的85.03。在所有制备的样品中，BSTNG-12由于其更高的密度和增强的结构致密性而表现出最有效的伽马辐射屏蔽性能。
