摘　　要：以ZrOCl2·8H2O和NaOH为原料,用水热法在200℃,12h下合成了单斜相纺锤形ZrO2纳米粒子,并通过改变相关实验条件,对ZrO2纳米粒子的形成机理进行了研究。利用X射线粉末衍射（XRD）、扫描电子显微镜（SEM）和电子能谱（EDS）等分析手段进行表征,结果表明,此方法合成的纺锤形ZrO2纳米粒子结晶形较好,纯度高,且能大量合成。Monoclinic zirconium oxide （ZrO2） nanospindles were synthesized by a hydrothermal method using zirconium oxychloride and sodium hydroxide as precursor at 200℃ for 12 h.The growth mechanism of ZrO2 nanospindles was also explored by changing some experimental conditions.The microstructure and morphology of the as-synthesized nanospindles were characterized by X-ray powder diffraction （XRD） , scanning electron microscopy （SEM） and electron diffraction spectra （EDS）.The results indicated that ZrO2 nanospindles have good nanostructure and high purity, and could be synthesized by large-scale.
