摘要
The core-shell structure in SrTiO<sub>3</sub> grains has been discovered with the analytical elec-tronic microscope （AEM）. Further studies show that the core-shell structure is formed due tothe inhomogeneous distribution of Pb and Bi ions, which may influence the physical propertiesof ceramics. Additionally, high-resolution lattice images reveal the partial edge-sharing ofoctahedra in the SrTiO<sub>3</sub> crystal lattice, and this kind of lattice defect is not common in thestructure of the ABO<sub>3</sub>-type ceramics.
