采用湿化学法制备成分为Ca_(0.85)Ce_(0.15)ZrTi_(1.85)Al_(0.15)O_7的钙钛锆石陶瓷固化体,借助于晶体结构拟合和扫描电子显微镜研究Ce离子在钙钛锆石陶瓷固化体中的固化行为和配位状态,结果表明:Ce~(3+)进入CaO8八面体中的钙位,而Al~(3+)作为电荷补偿进入半占据的TiO5五面体中。通过产品一致性测试法测试固化体的化学稳定性。抗浸出性能研究表明固化体可稳固存在于深地质处置条件下,Ce元素的标准化抗浸出率达到10-5g·m-2·d-1数量级。 A wet-chemical method was used to prepare a solidified zirconia-zirconia ceramic with Ca_ (0.85) Ce_ (0.15) ZrTi_ (1.85) Al_ (0.15) O_7. The crystal structure and scanning electron microscopy The results show that Ce ~ (3 +) enters the calcium sites in CaO8 octahedron, and Al ~ (3 +) compensates the charges into semi-occupied TiO5 pentahedrons. The chemical stability of the cured body was tested by the product conformance test method. Anti-leaching performance studies show that the solidified body can be firmly in the deep geological disposal conditions, the standard anti-leaching rate of Ce element of 10-5g · m-2 · d-1 order of magnitude.
