研究以钛酸丁酯和氯化锶为原料,采用溶胶-沉淀法合成纳米钛酸锶(SrTiO3),通过对产物X射线衍射分析,可知NaOH浓度对产物结构具有较大影响;研究不同淀粉添加量与纳米SrTiO3粒度分布之规律,通过改变淀粉配量可有效地控制纳米SrTiO3粒度分布;通过透射电子显微镜和扫描电子显微镜对产品形态和结构进行表征,所得纳米SrTiO3形态比较规则,多数呈球形颗粒,单分散性好,粒径分布为30～80nm。讨论溶胶-沉淀法制备纳米SrTiO3的反应过程,阐明淀粉对纳米SrTiO3粒度调控作用。
In this paper, strontium titanate (SrTiO3) was synthesized by sol-precipitation method using butyl titanate and strontium chloride as raw materials. The XRD results showed that the concentration of NaOH had a significant effect on the product structure. The particle size distribution of nano SrTiO3 and the rules of nano-SrTiO3 particle size distribution can be effectively controlled by changing the particle size distribution of SrTiO3 nano-SrTiO3 by transmission electron microscopy and scanning electron microscopy morphological and structural characterization of the resulting nano-SrTiO3 morphology rules, the majority of spherical particles , Monodispersity, particle size distribution of 30 ~ 80nm. The reaction process of preparing SrTiO3 nanocomposite by sol-precipitation method was discussed, and the effect of starch on the particle size regulation of nanoscale SrTiO3 was clarified.
