Abstract
The characteristics of domain were studied by chemical etching and x-ray analysis for the tetragonal phase PZT ceramics with a tetragonality of c/a = 1.041 to 1.027. The morphologies of domain on the surface were different from those in inner parts of the specimen and the anisotropy of 90 domain arrangement increased with increasing tetragonality. After poling, the amount of microcracks increased with tetragonality and poling field, and these microcracks reduced dielectric constant.Keywords
