Preparation method and application of uranium-doped high-entropy pyrochlore solidified body
The invention belongs to the technical field of high-radioactivity nuclear waste treatment, and particularly relates to a high-entropy pyrochlore ceramic solidified body and a preparation method and application thereof. The invention provides the preparation method of the high-entropy pyrochlore ceramic solidified body, and the high-entropy pyrochlore ceramic solidified body contains elements of lanthanum, praseodymium, europium, gadolinium, ytterbium, uranium and zirconium contained in high-level liquid waste so as to enhance the adaptability of the high-entropy pyrochlore ceramic solidified body to waste elements. According to the invention, a plurality of nuclides can be coordinated, and a plurality of key nuclides can be solidified. Meanwhile, the anti-leaching performance of a solidified body can be improved, and migration and diffusion of radionuclides are effectively prevented.
本发明属于高放射性核废物处理技术领域，更具体地，涉及一种高熵烧绿石陶瓷固化体及其制备方法和应用。提供了一种高熵烧绿石陶瓷固化体的制备方法，其包含了高放废液所含元素镧、镨、铕、钆、镱、铀及锆，以增强其对废物元素的适应性。其能对多种核素进行协调处理，可对多种关键核素进行固化。同时其能提升固化体的抗浸出性能，有效阻止放射性核素的迁移扩散。
