摘　　要：本文采用液相和煅烧相结合的方法合成了微纳米结构Co_3O_4陶瓷材料,并对其微观结构和介电性能进行了研究。通过X-射线衍射(XRD),扫描电镜(SEM),透射电镜(TEM)和高分辨透射电镜(HRTEM)表征手段,对产品的微观结构进行了表征。并进一步对两种微纳米结构Co_3O_4的介电性能进行了研究,研究结果表明多孔花状结构Co_3O_4材料具有良好的介电性能。Micro-nanostructure Co3O4 ceramics were prepared by the combination of solution-phase method and calcination treatment. The microstructure and dielectric properties of the as-prepared samples were then characterized by XRD, SEM, TEM and HRTEM. Furthermore, the dielectric properties of the Co3O4 powders of two di fferent micro-nanostructures were researched. Results show the porous flower-like Co3O4 ceramics had excellent performances.
