摘要： 采用水热晶化法制备了Ｂａ（ＳｂⅢ，ＳｂⅤ）Ｏ３新型钙钛矿型氧化物，并通过ＸＲＤ、 ＩＲ、ＳＥＭ和ＩＣＰ等方法对产物物相、形貌和组成等进行了表征．结果表明，产物为立方钙钛矿结构，晶胞参数为α＝０．４１５ｎｍ，粒度为１～２μｍ具有一定团聚的多晶粉末．产物中锑为三价和五价两种价态．水热条件对合成影响的研究结果表明， Ｂａ（ＳｂⅢ，ｓｂⅤ）Ｏ３合成的适宜碱度和ｎＳｂ（Ⅴ)／ｎＳｂ（Ⅲ）分别为 ８～１０Ｍｏｌ／Ｌ ＫＯＨ和 ０～１

Abstract: A novel double perovskite-type oxide Ba(Sb Ⅲ, SbⅤ)O3 was synthesized by hydrothermal crystallization methods. The phase,
morphology and particle size of the product were characterized by XRD, IR, SEM and ICP techniques. The results indicated that the
Ba(Sb Ⅲ,SbⅤ)O3 oxide shows a cubic perovskite-type structure with a cell parameter a=0.415nm, and has a particle size in the range from 1 to 2μm.
The product has trivalent and pentavalent two states antimony ions. The influence of hydrothermal conditions exhibited that the optimum
alkalinity and nSb( Ⅲ)/nSb(Ⅴ) are 8～10 mol/L KOH medium and 0～1 respectively.

Key words: hydrothermal synthesis, perovskite, oxide, antimonate
