摘要
以正丁胺为溶剂,在150℃反应72h制备了超细BaTiO3纳米颗粒。利用X射线粉末衍射(XRD),扫描电镜(SEM),透射电镜(TEM)和高分辨透射电镜(HRTEM)分析表征了所得样品的形貌、尺寸和结构特征,并考察了正丁胺在BaTiO3纳米颗粒制备过程中的作用。结果表明,BaTiO3纳米颗粒为立方相结构,颗粒平均直径约为20nm,正丁胺作为模板剂,在合成过程中有效地抑制了BaTiO3纳米颗粒的生长。
Ultrafine BaTiO3 nanoparticles were prepared in n-butylamine under non-aqueous solvothermal condition at 150℃ for 72 h. The as-prepared BaTiO3 nanoparticles were characterized by XRD, SEM and TEM （HRTEM）, and the effect of n-butylamine as solvent was also investigated. The results show that the as-prepared BaTiO3 nanoparticles are cubic phase with mean diameter of 20 nm. The n-butylamine plays a vital role as template in hindering the growth of BaTiO3 nanoparticles.
