Abstract

As a fission product in high‐level radioactive nuclear waste, Mo has low solubility in borosilicate glass. Fe2O3 is not only a prevalent transition metal element but also a major corrosion product in high‐level radioactive nuclear waste. Against this backdrop, the effect of Fe2O3 content on the structure and chemical durability of typical molybdenum‐containing sodium borosilicate glasses for nuclear waste immobilization are studied. The results show that the samples containing more than 3.85 mol% Fe2O3, a completely homogenous amorphous glass sample is obtained. Moreover, the mechanism of the effect of Fe2O3 on the solubility of Mo is discussed in detail. In this work, a portion of Fe3+ is reduced to Fe2+ and enters into the glasses as a charge compensation ion as Fe2+O6. Concurrently, Fe3+ ions contribute to the formation of the glass networks as Fe3+O4. Iron incorporation can improve the chemical durability of the sample.

Fe2O3 对用于固定核废料的含 Mo 硼硅玻璃的结构和性能的影响
作为高放射性核废料中的裂变产物,钼在硼硅玻璃中的溶解度很低。Fe2O3 不仅是一种常见的过渡金属元素,也是高放射性核废料中的主要腐蚀产物。在此背景下,研究了 Fe2O3 含量对用于固定核废料的典型含钼硼硅酸钠玻璃的结构和化学耐久性的影响。结果表明,Fe2O3 含量超过 3.85 mol% 的样品可得到完全均匀的无定形玻璃样品。此外,还详细讨论了 Fe2O3 对钼溶解度的影响机制。在这项工作中,一部分 Fe3+ 被还原成 Fe2+,并作为电荷补偿离子以 Fe2+O6 的形式进入玻璃。同时,Fe3+ 离子以 Fe3+O4 的形式参与玻璃网络的形成。铁的加入可以提高样品的化学耐久性。

期刊介绍: The International Journal of Applied Glass Science (IJAGS) endeavors to be an indispensable source of information dealing with the application of glass science and engineering across the entire materials spectrum. Through the solicitation, editing, and publishing of cutting-edge peer-reviewed papers, IJAGS will be a highly respected and enduring chronicle of major advances in applied glass science throughout this century. It will be of critical value to the work of scientists, engineers, educators, students, and organizations involved in the research, manufacture and utilization of the material glass. Guided by an International Advisory Board, IJAGS will focus on topical issue themes that broadly encompass the advanced description, application, modeling, manufacture, and experimental investigation of glass.
