摘要
铁磷酸盐材料是一类新型的核废物固化材料,铁磷酸盐玻璃具有较高的化学稳定性和较低的熔融温度,独居石、磷灰石等是固化核素优选的晶体,铁磷酸盐玻璃陶瓷固化兼有玻璃基体对多种元素的包容性和陶瓷固化对特定放射性核素抗辐射能力的优势。综述了铁磷酸盐玻璃、陶瓷及玻璃陶瓷的特点及其在高放废物固化方面的研究现状及进展,比较了用于核废物固化的铁磷酸盐固化体的体系及特点。
Iron phosphate material is a new type of material for nuclear waste solidification. Iron phosphate glass shows better corrosive-resistant and lower melting temperature. Monazite, apatite are optimized crystals of curing nuclide. Immobilization as a Iron phosphate glass-ceramic wastform has advantages both high Immobilization capacity of glass for multiple elements and radiation resistance of ceramic for curing specific radionuclide. In this paper some features and the research progress of the iron phosphate glass, ceramic and glass-ceramic in nuclear waste solidification were discussed. The system and characteristics of the iron phosphate solidified body for nuclear waste solidification were compared.
