| 摘 要： | 以氧化铁、钛粉、氧化钙、二氧化钛为原料,利用溶胶-凝胶反应制备了人造钙钛矿岩石。以人造岩石为基底,利用固相反应固化模拟放射性核素Sr。借助X射线衍射(XRD)、扫描电子显微镜(SEM)等方法分析固化体形貌与结构。结果分析表明:当Fe2O3∶Ti∶CaO∶TiO2=2∶3∶4∶1(物质的量之比),掺入SrO含量为10%时,可以获得较好的钙钛矿物相。

| Abstract: | Perovskite synroc was synthesized by the sol-gel method,using Fe2O3,Ti,CaO and TiO2 as main raw materials,and simulated radioactive element Sr was immobilized in pervoskite synroc matrix through solid-state reaction.The as-formed sample was then analyzed by X-ray diffraction and scanning electron microscopy.The results indicate that the best result can be obtained when the mol ratio of Fe2O3∶Ti∶CaO∶TiO2=2∶3:4:1 and the doping amount of SrO is 10%. |
