| Summary: | The microstructure of PbZr0.9Ti0.1O3 ceramics is studied by transmission electron microscopy.
Two types of domain patterns are found, namely, the 109° domain with the F spots ( 1/2{hkl}
superlattice reflections) observed in neighboring domains and the 71° domain with the F spots
observed in one domain and having disappeared in the neighboring one. The computer simulation
indicates that the F spots are forbidden at h=k positions so that they do not appear in the electron
diffraction pattern if viewed along the [110] direction. Based on this result, the observed two types
of domain patterns and their corresponding diffraction patterns can be explained. |
