锆石的合成及其固化核废物应用研究

Synthesis of Zircon and Its Application in the Immobilization of Nuclear Waste

锆石因其优异的物理化学性质,除在地质测年、陶瓷、玻璃、耐火材料及铸造等诸多领域得以广泛应用外,在核废物固化处理中也展现出良好应用前景,因此锆石是一种战略性非金属矿产。概述了国内外锆石固化核废物的研究现状,重点介绍了锆石基核废物固化体的合成方法,锆石对模拟锕系核素的固化行为,锆石固化体的热稳定性、化学稳定性及辐照稳定性等方面的研究工作,并展望了今后锆石研究的发展方向。

Zircon has been widely used in the field of geological dating,ceramics,glass,refractories and casting,and also has a good application prospect in the field of the immobilization of nuclear waste,due to its excellent physical and chemical properties.Therefore,zircon is a strategic non-metallic mineral.In this paper,the research on the immobilization of nuclear waste using zircon is summarized.The synthesis methods,simulated actinides immobilization behavior,thermal stability,chemical stability and irradiation stability of zircon waste form are introduced.Furthermore,the development in the future research of zircon is prospected.
