This work investigated the gamma ray attenuation power of barium calcium aluminosilicate glass by using silicon carbide nanotube modifiers. Shielding efficiency of BaO–15CaO–5Al2O3–10B2O3–35SiO2 was investigated by adding different concentrations of silicon carbide nanotubes (10, 15, 20, 25 mol %). Amorphous and fine characteristics of the prepared glass materials were analyzed using XRD and FTIR techniques. In the results obtained, absence of sharp peaks in the XRD pattern revealed that the prepared glass was amorphous. Analysis of the radiation shielding properties was tested against gamma radiation by using PHY-X/PSD software. Various shielding parameters such as linear attenuation coefficient, mass attenuation coefficient, half value layer, tenth value layer, mean free path, and effective atomic number were determined to access the radiation shielding strength of the prepared samples. From the obtained results, composites of barium calcium aluminosilicate and silicon carbide nanotubes (sample 1) with higher values of mass attenuation coefficient (32.92 cm/g) and effective atomic number (52.02) provided superior gamma ray attenuation. Results also revealed that the density and chemical composition of the prepared glass samples strongly influence photon interactions and weakly influence electronic interactions during the photon attenuation process. The results demonstrated that increasing the weight fractions of silicon carbide nanotubes in the glass samples increases the shielding properties.

碳化硅纳米管增强钡钙铝硅酸盐玻璃材料辐射屏蔽性能研究


本工作利用碳化硅纳米管改性剂研究了钡钙铝硅酸盐玻璃的伽马射线衰减能力。通过添加不同浓度的碳化硅纳米管（10、15、20、25 mol%），研究了 BaO–15CaO–5Al2O3–10B2O3–35SiO2 的屏蔽效率。利用 XRD 和 FTIR 技术对所制备的玻璃材料的非晶态和精细特性进行了分析。在获得的结果中，XRD 图案中不存在尖峰表明所制备的玻璃是非晶态的。使用 PHY-X/PSD 软件对伽马辐射的辐射屏蔽性能进行了分析。测定线性衰减系数、质量衰减系数、半值层、十值层、平均自由程和有效原子序数等各种屏蔽参数，以获得所制备样品的辐射屏蔽强度。从获得的结果来看，具有较高质量衰减系数（32.92 cm/g）和有效原子序数（52.02）的铝硅酸钡钙和碳化硅纳米管复合材料（样品1）提供了优异的伽马射线衰减。结果还表明，所制备的玻璃样品的密度和化学成分对光子衰减过程中的光子相互作用有强烈影响，而对电子相互作用影响较弱。结果表明，增加玻璃样品中碳化硅纳米管的重量分数可以提高屏蔽性能。
