In this study, a group of molybdenum boro-tellurite glass samples and their mechanical parameters and nuclear radiation shielding competencies were investigated. The amorphous structures of molybdenum boro-tellurite glasses were confirmed by XRD patterns. Synergistic positive effect of MoO3 reinforcement on gamma ray attenuation properties and mechanical parameters was investigated. For this aim, and in the energy range 0.015–15 MeV, the mass attenuation coefficients (MAC) had been computed by computational methods. At 0.015 MeV, the MAC values increase from 28.06 to 33.25 (cm2 g−1) as the MoO3 content increases from 0 to 30 mol %, while the half value layer values decrease from 4.84 to 3.88 (cm) at 15 MeV. The longitudinal ultrasonic velocity (VL) and shear ultrasonic velocity (VS), longitudinal modulus (L), shear modulus (S), bulk modulus (K), and Young’s modulus (Y) increase from 3450 to 3637 (m s−1), from 1994 to 2146 (m s−1), from 53.44 to 64.88 (GPa), from 17.86 to 22.58 (GPa), from 29.63 to 34.77 (GPa), and from 44.61 to 55.69 (GPa), respectively. The analysis of the shielding and mechanical indicates best protection of the explored glasses for γ-irradiation. Based on the analysis, the glass 30MoO3-70TeO2 with the maximum MoO3 addition indicated best γ-irradiation protection and mechanical parameters among the explored glasses.

一些用三氧化钼增强的碲酸盐玻璃的机械,结构和核辐射屏蔽能力

在这项研究中,研究了一组钼硼-碲玻璃样品及其力学参数和核辐射屏蔽能力。X射线衍射图证实了硼硼铁矿钼玻璃的非晶结构。研究了MoO 3增强剂对γ射线衰减特性和力学参数的协同正效应。为此,在0.015–15 MeV的能量范围内,已经通过计算方法计算了质量衰减系数(MAC)。在0.015 MeV下,随着MoO3含量从0到30 mol%增加,MAC值从28.06增加到33.25(cm 2 g-1),而在15 MeV下半值层值从4.84减小到3.88(cm)。纵向超声波速度(V L)和剪切超声速度(VS),纵向模量(L),剪切模量(S),体积模量(K)和杨氏模量(Y)从3450增加到3637(ms -1),从1994年增加到2146( ms -1),从53.44至64.88(GPa),从17.86至22.58(GPa),从29.63至34.77(GPa)和从44.61至55.69(GPa)。对屏蔽和机械性能的分析表明,所探查的玻璃具有最佳的γ射线防护能力。根据分析,在所探究的玻璃中,添加了最大MoO 3的玻璃30MoO 3 -70TeO 2表现出最佳的γ辐射防护性能和力学参数。
