Glass samples of structural formula (55B2O3–15SiO2–30Na2O: xWO3; with x = 0.0, 0.5, 1.0 and 1.5 weight percent) were prepared by melting and rapid quench route. Quantities of H3BO4, SiO2, Na2CO3 and WO3 were calculated, well milled and then placed in a muffle oven at a temperature of 1050 °C for 30 min. The stainless steel mold heated at 200 °C and then the melt poured between the plates to get transparent glass disks. The X-ray diffraction technique applied to glass samples with the Rigaku XRD-6000 diffractometer confirmed the amorphous structure of these glass samples. Both indirect and direct Eg show a gradual decrease trend as the concentrations of WO3 content. Makishima–Mackenzie's theory was applied to evaluate the elastic properties of the present glass system, and then, the obtained results were compared with different theoretical models. Additionally, the radiation shielding efficiency of the prepared borosilicate glass system was evaluated and interpreted based on the electromagnetic models via Geant4 simulations. The results obtained by Geant4 were compared with the predictions of theoretical values calculated by PSD software in terms of mass attenuation coefficients (MACs). The results reveal that our prepared borosilicate glass system has potential use in radiation shielding applications, wherein the balance between elastic and shielding properties can be controlled by changing the concentration of WO3 according to the desired application.

WO3掺入对硼硅玻璃体系合成、光学、弹性和辐射屏蔽性能的影响

结构式(55B 2 O 3 –15SiO 2 –30Na 2 O:x WO 3x  = 0.0、0.5、1.0和1.5重量百分比)的玻璃样品通过熔融和快速淬火路线制备。H 3 BO 4、SiO 2、Na 2 CO 3和WO 3 的量计算好,研磨好,然后放入马弗炉中,温度为 1050 °C 30 分钟。不锈钢模具在 200 °C 下加热,然后将熔体倒入板之间以获得透明玻璃盘。使用理学 XRD-6000 衍射仪对玻璃样品进行 X 射线衍射技术证实了这些玻璃样品的无定形结构。随着WO 3浓度的增加,间接E g和直接E g 均呈现逐渐降低的趋势。内容。Makishima-Mackenzie 理论被应用于评估本玻璃系统的弹性性能,然后将获得的结果与不同的理论模型进行比较。此外,基于电磁模型通过 Geant4 模拟对制备的硼硅酸盐玻璃系统的辐射屏蔽效率进行了评估和解释。将 Geant4 获得的结果与 PSD 软件在质量衰减系数 (MAC) 方面计算的理论值的预测进行了比较。结果表明,我们制备的硼硅玻璃体系在辐射屏蔽应用中具有潜在用途,其中弹性和屏蔽性能之间的平衡可以通过根据所需应用改变 WO 3的浓度来控制。
