Abstract

Effective disposal of radioactive waste is crucial for safe development of nuclear energy. In this study, flash sintering technology is used for the first time to quickly solidify simulated Sr-contaminated soil waste. The waste can be converted into a glass–ceramic phase by heating the waste at 1100 °C for 1 min during flash sintering. The phase evolution during flash sintering as a function of density and amorphous fraction was systematically investigated. Additionally, the microstructural evolution of the matrices and the leaching behavior of simulated waste elements (e.g., Sr) were evaluated. This study explores the feasibility of using flash sintering for treating radioactive contamination waste.

闪速烧结玻璃陶瓷处理锶污染土壤废弃物

有效处置放射性废物对核能的安全发展至关重要。本研究首次采用闪速烧结技术来快速固化模拟锶污染土壤废物。在闪速烧结过程中，通过在 1100 °C 下加热 1 分钟，可将废料转化为玻璃陶瓷相。系统研究了闪速烧结过程中相的演变与密度和无定形部分的函数关系。此外，还评估了基质的微观结构演变和模拟废物元素（如锶）的浸出行为。这项研究探讨了利用闪速烧结处理放射性污染废物的可行性。
