摘　　要：采用溶胶凝胶法制备了（Sm1-xErx）2Zr2O7纳米粉体,采用XRD和FT-IR技术分析了粉体的相组成,用SEM和EDS分析了粉体的显微形貌和元素组成.结果表明,采用溶胶凝胶法成功地制备了纯净的具有焦绿石结构的（Sm1-xErx）2Zr2O7纳米粉体,其颗粒尺寸为30-200 nm,各元素摩尔比与化学式一致.The （Sm1-xErx）2Zr2O7 powders were prepared by sol-gel method in this paper. The phase structure was analyzed by XRD and FT-IR methods,the mico-morphology and element composition were investigated by SEM and EDS. Results show that pure powders with pyrochlore structure are synthesized successfully,the particle size lies in the range of 30 - 200 nm and the atomic ratio of elements is consistent to their chemical expression.
