采用新型的喷雾技术，在600-800°C下煅烧，成功地合成了光滑、球形的ZrO 2颗粒。采用扫描电子显微镜（SEM）、透射电子显微镜（TEM）、高分辨透射电子显微镜（HRTEM）和X射线衍射（XRD）对合成的ZrO 2微球进行了表征。结果表明，合成的ZrO 2微球主要以c相存在，具有均匀的介孔结构，由宽径约8- 13 nm的花生状纳米颗粒组成。
Smooth and spherical ZrO2particles were successfully synthesized by a novel spray technique and calcination at 600–800°C. The synthesized ZrO2microspheres were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and X-ray diffraction (XRD). It was found that the synthesized ZrO2microspheres, which were mainly existed as c-phase, possessed a homogeneously mesoporous microstructure consisting of peanut-like nano-grains around 8–13nm in width diameter.
