摘要

本文根据化学式（7 + x）PbO2-(18 + y)BaO- 12cao -(63-x-y-z)B2O3-z Pr6O11，合成并表征了不同浓度PbO2、BaO和Pr6O11增强的新型硼酸盐基玻璃系列；x = y = 0, 1, 2,和3摩尔%,而z = 0, 0.5, 1.0,和1.5 mol %。研究了PbO2、BaO和Pr6O11化合物的配比对其结构、光学、机械和辐射屏蔽特性的影响。结果表明，PbO2 + BaO + Pr6O11取代B2O3的浓度在25 ~ 32.5 mol%范围内增加，直接能带隙减小3.08 ~ 2.82 eV。利用红外光谱法确定了合成玻璃的吸收带和相应的红外主动振动模式。采用Makishima Makinzie模型分析了玻璃的力学模量和力学性能。在25 ~ 32.5 mol.%的浓度范围内，PbO2 + BaO + Pr6O11浓度的增加使制备样品的显微硬度从4.985略微降低到4.736 GPa。

Exploration of the effects of corporate lead, barium, and praseodymium oxides on mechanical, optical, structural, and gamma-ray shielding properties of borate-based glasses

This work deals with the synthesis and characterization of a new borate-based glass series reinforced with various concentrations of PbO₂, BaO, and Pr₆O₁₁ according to the chemical formula of (7 + x)PbO₂-(18 + y)BaO-12CaO-(63-x-y-z)B₂O₃-z Pr₆O₁₁; x = y = 0, 1, 2, and 3 mol%, while z = 0, 0.5, 1.0, and 1.5 mol%. The influence of the corporation of PbO₂, BaO, and Pr₆O₁₁ compounds on the structural, optical, mechanical, and radiation shielding characteristics was investigated. The evaluation shows that the raise in substitution of PbO₂ + BaO + Pr₆O₁₁ for B₂O₃ across the concentration of 25–32.5 mol% decreases the direct energy band gap between 3.08 and 2.82 eV. The absorption bands and corresponding IR active vibrational modes were identified for the synthesized glasses using FTIR spectrometry. The Makishima Makinzie model was applied to understand the behavior of mechanical modulus and mechanical properties for the glasses. The increase in PbO₂ + BaO + Pr₆O₁₁ throughout a concentration range of 25–32.5 mol.% decreases slightly the microhardness of the prepared samples from 4.985 to4.736 GPa.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
