摘要: 利用水热晶化法制备了Ba₂SbInO₆纯相，并通过XRD、SEM、IR、XPS和ICP等方法，对产物的物相、形貌、结构和组成进行了表征。初步结构表征结果表明，产物可能为B位离子无序排列的立方钙钛矿结构，空间群为Pm3m，晶胞参数为a=0.4132 mm。产物粉末呈现立方晶型，粒度约为0.5～2 μm。

Abstract: Double perovskite-type Ba₂SbInO₆ was prepared by hydrothermal method. The phase, morphology, structure and Ba∶Sb∶In ratio were characterized by the techniques such as XRD、SEM、IR、XPS and ICP method. The results indicated that the phase is cubic perovskite-type structure. Its B-cations exhibits radom arrangement with a cell parameter a=0.4132 nm. The space group of Ba₂SbInO₆ is Pm3m. The powders of Ba₂SbInO₆ shown a cubic shape in which grain sizes are 0.5～2 μm.

Keywords: hydrothermal synthesis double perovskite Ba₂SbInO₆ oxide
