Abstract

The influence of B³⁺ and Pb²⁺ ions on the electrical and mechanical properties of a borate network was extensively studied. A 30B₂O₃–10ZnO–60Na₂O core network was prepared using the commercial melt/quenching technique and inlaid by different concentrations of B₂O₃ + Pb₃O₄ at the expense of Na₂O. The impact of Pb²⁺ and B³⁺ ions on the mechanical properties were studied through ultrasonic wave velocities, elastic moduli, and microhardness. The more bridging oxygens BO₄ that brought to the considered borate network due to the more addition of B₂O₃ and conversion of BO₃ to BO₄ via Pb²⁺ ions penetration, formation of PbO₆, and formation of the strong bonds B–O–Pb reinforced elastic moduli and microhardness of the studied borate network. Electrical properties through dielectric constant, electric modulus, impedance, and ac conductivity were extensively studied. The dielectric constant and electric modulus showed a behavior up to 20 mol % of Pb²⁺ and 35 mol % of B³⁺ differs from after that concentration, while ac conductivity differs at 40 mol % of Pb²⁺ and 50 mol % of B³⁺ from before that concentration. The results of the dependence of conductivity on frequency and temperature showed that the considered glass have a semiconducting nature.

摘要

^{人们广泛研究了B 3+}和Pb ²⁺离子对硼酸盐网络的电学和机械性能的影响。采用商业熔化/淬火技术制备了30B ₂ O ₃ –10ZnO–60Na _{2 O 核网络，并以不同浓度的 B 2} O ₃ + Pb ₃ O ₄镶嵌，以牺牲 Na _{2 O 为代价。 Pb} ²的影响通过超声波速度、弹性模量和显微硬度研究了⁺和B ^{3+离子对机械性能的影响。}由于添加了更多的 B ₂ O ₃以及通过 Pb ^{2+离子渗透将 BO} ₃转化为 BO ₄，形成了 PbO ₆，并形成了强键 B，因此更多的桥氧BO ₄被引入到所考虑的硼酸盐网络中–O-Pb 增强了所研究的硼酸盐网络的弹性模量和显微硬度。通过介电常数、电模量、阻抗和交流电导率等电气特性进行了广泛的研究。介电常数和电模量表现出高达 20 mol% Pb ²⁺和 35 mol% B ³⁺浓度后的行为与该浓度后的情况不同，而交流电导率在 40 mol% Pb ²⁺和 50 mol% B 时有所不同与该浓度之前相比，^{3+ 。}电导率对频率和温度的依赖性结果表明，所考虑的玻璃具有半导体性质。
