摘要

The polymorphic structure evolution of (Ba,Ca)(Zr,Ti)O₃ piezoelectric ceramics was investigated by analysis of the in situ X-ray diffraction and dielectric spectra. The results indicated that a confined orthorhombic (O) phase region induced by the approach of the rhombohedral (R) and tetragonal (T) phases existed in an extremely narrow temperature range of (Ba_0.85Ca_0.15)(Zr_0.1Ti_0.9)O ₃ composition. The electric properties near the O-T phase boundaries of (Ba_0.95Ca_0.05)(Zr_0.05Ti_0.95) O₃ and (Ba_0.85Ca_0.15)(Zr_0.1Ti _0.9)O₃ were compared. The results suggested that the confined O phase region is an important factor that contributes to the extremely large piezoelectric response.
