Abstract

Antimony zinc borate glasses with compositions (45-m)ZnO-(55-n)BO-(m + n)SbO (0 ≤ m, n ≤ 15 mol%) were synthesized via the melt-quenching technique to investigate the impact of SbO substitution on structural, thermal, and radiation shielding properties. X-ray diffraction confirmed the amorphous nature of the synthesized glass samples. Fourier-transform infrared spectroscopy revealed significant structural rearrangements, including an increase in non-bridging oxygen content with rising SbO concentrations, as evidenced by the shifting and intensification of characteristic absorption bands. Differential thermal analysis demonstrated that the glass transition temperature decreased from 580 °C to 490 °C with increasing SbO, while the thermal stability parameter (ΔT) improved from 144 °C to 256 °C, particularly when BO was replaced. Density increased from 3.121 g/cm to 3.836 g/cm, and molar volume expanded from 24.01 cm/mol to 31.16 cm/mol. Radiation shielding performance was significantly enhanced: at 10 MeV, the linear attenuation coefficient increased from 0.0768 cm to 0.1142 cm (~ 49%) when replacing BO and to 0.0983 cm (~ 28%) when replacing ZnO. The half-value layer decreased from 9.02 cm to 6.07 cm at 15 mol% SbO, confirming improved photon attenuation. Overall, this work offers valuable insights into the interplay between composition, structure, and functional properties in SbO-doped zinc borate glasses.

摘要

通过熔体淬火技术合成了组成为(45 - m)ZnO-(55 - n)BO-(m + n)SbO（0 ≤ m, n ≤ 15 mol%）的锑锌硼酸盐玻璃，以研究SbO取代对结构、热性能和辐射屏蔽性能的影响。X射线衍射证实了合成玻璃样品的非晶态性质。傅里叶变换红外光谱揭示了显著的结构重排，包括随着SbO浓度的增加非桥氧含量增加，这由特征吸收带的位移和增强所证明。差示热分析表明，随着SbO含量的增加，玻璃化转变温度从580℃降至490℃，而热稳定性参数(ΔT)从144℃提高到256℃，特别是在BO被取代时。密度从3.121 g/cm增加到3.836 g/cm，摩尔体积从24.01 cm/mol扩大到31.16 cm/mol。辐射屏蔽性能显著增强：在10 MeV时，当取代BO时，线性衰减系数从0.0768 cm增加到0.1142 cm（约49%），当取代ZnO时增加到0.0983 cm（约28%）。在15 mol% SbO时，半值层从9.02 cm降至6.07 cm，证实了光子衰减的改善。总体而言，这项工作为掺杂SbO的锌硼酸盐玻璃中成分、结构和功能特性之间的相互作用提供了有价值的见解。
