| 摘 要： | 为研制出耐辐照的新型单相陶瓷燃料，采用溶胶-凝胶法，通过复合溶胶配制、分散胶凝、洗涤、干燥煅烧与烧结过程，开展了UO2-(Zr0.8Ca0.2)O1.8燃料微球制备工艺研究，制备出铀摩尔分数含量分别为30mol%、50mol%、70mol%的UO2-(Zr0.8Ca0.2)O1.8燃料微球样品。在对工艺过程进行分析的基础上，通过实验确定了工艺参数。采用X射线衍射（XRD）对3种燃料微球样品进行分析，分析结果表明:铀摩尔分数含量分别为30mol%、50mol%、70mol%的UO2-(Zr0.8Ca0.2)O1.8燃料微球样品均为面心立方（FCC）固溶体结构。

| Abstract: | In order to develop the single-phase ceramic fuel with good radiation resistance,the UO2-(Zr0.8Ca0.2)O1.8 microspheres with different uranium contents (30mol%,50mol%,70mol%)were prepared by Inner-Sol-Gel technique.The technique is with five processes including sol preparation,casting and gelation,washing,drying,and sintering.The parameters of this technique were fixed on the basis of analysis and experiment.The UO2-(Zr0.8Ca0.2)O1.8 spheres were analyzed by XRD.The results show that UO2-(Zr0.8Ca0.2)O1.8 microspheres with different uranium contents(30mol%,50mol%,70mol%) were FCC solid solution. |
