玻璃的辐照效应及耐辐照改性研究进展

航天科技、核医学、核能工业和绿色建筑的发展对使用在辐射环境中的玻璃提出了越来越高的要求。玻璃在辐射环境中会发生微观结构变化和宏观性质改变,耐辐照玻璃是一种在高能射线或粒子辐照后可见光区透过率下降较小,能保持物理化学性能稳定的特种玻璃。阐述了玻璃的辐照效应研究现状,介绍了玻璃耐辐照改性的研究进展及挑战,并提出了值得关注的新趋势。

Irradiation Effects and Irradiation Resistance Modification of Glasses

With the development of aerospace science and technology, nuclear medicine, nuclear power industry and green architecture, more rigorous requirements on glasses used in radioactive environment have been put forward. Irradiation may cause va-riations in glass microstructure and in glass macroscopic properties, and irradiation resistant glass should specifically possess stabilized physicochemical performances with little drop in visible light transmittance. This paper introduces the current research status on glass irradiation effects. Furthermore, progress and challenges of irradiation-resistant modification on glasses are reviewed with some notable new trends proposed.
