Abstract

SEM investigations of ferroelectric domain structure in PbZr0.53Ti0.47O3 are consistent with a model of spatial domain configuration for the piezoelectric ceramics previously proposed for BaTiO3. TEM and SAED results revealed not only the twinning relation of adjacent tetragonal 90° domains but also the simultaneous presence of the ferroelectric rhombohedral phase. A succession model of ferroelectric domains T1RT2RT1... which needs a smaller energy for the rotation of the polarization vector due to the coexistence of a R domain between the two T 90° domains is proposed. This model is also confirmed by the estimated value of elastically stored energy in the mixed wall and by the dependence upon the sintering temperature of T and R unit cell distortions previously measured by x-ray diffraction.
