The main goals of this current work are to study the elastic and radiation shielding properties of seven different compositions of ZnO-TeO2 transparent glass and characterize them using density, molar volume, X-ray diffraction (XRD), ultrasonic technique, and Monte Carlo simulation method. From the ultrasonic wave measurement result, the substitution of ZnO, which works as a network modifier into the TeO2 glass systems, would break up the Te-O-Te bonds of TeO4 into the form TeO3 along with all the formation of NBO's which give the impact on the elastic moduli analysis. The radiation shielding features for the fabricated samples were studied using the MCNP-5 code. The difference between the MCNP and XCOM results was found to be less than 3%. The highest linear attenuation coefficient (LAC) for all ZT glasses achieved at 0.015 MeV and varied between 202.199 and 239.607 cm−1 for glasses coded 0 ZT and 30ZT, respectively.

使用 MCNP-5 模拟代码的 ZnO 对碲酸盐玻璃体系物理、弹性和伽马辐射屏蔽性能的影响

目前这项工作的主要目标是研究 ZnO-TeO 2透明玻璃的七种不同成分的弹性和辐射屏蔽性能,并使用密度、摩尔体积、X 射线衍射 (XRD)、超声波技术和蒙特卡罗来表征它们模拟方法。从超声波测量结果来看,作为网络改性剂的 ZnO 替代到 TeO 2玻璃体系中,会使 TeO 4的 Te-O-Te 键断裂成 TeO 3的形式以及对弹性模量分析产生影响的所有 NBO 的形成。使用 MCNP-5 代码研究了制造样品的辐射屏蔽特性。发现 MCNP 和 XCOM 结果之间的差异小于 3%。所有 ZT 玻璃的最高线性衰减系数 (LAC) 达到 0.015 MeV,编码为 0 ZT 和 30ZT 的玻璃的线性衰减系数 (LAC) 分别在 202.199 和 239.607 cm -1之间变化。
