Abstract

The domain structures and piezoelectric properties of polycrystalline orthorhombic 0.5(Ba0.7Ca0.3)TiO3‒0.5Ba(Zr0.2Ti0.8)O3 (BCZT50) polarized by various poling methods were investigated. Semiquantitative analysis using a scanning electron microscope revealed that the domain size dD of BCZT50 polarized by alternating current poling (AC-poling, dD = 0.16 µm) and unipolar pulse poling (Uni-poling, dD = 0.16–0.36 µm) were finer than those in samples polarized by conventional direct current poling method (DC-poling, dD = 0.32 µm). Although the domain size of the Uni-poled sample was intermediate among the three different poling methods, the highest piezoelectric charge coefficient d33 of 339 pC/N was achieved by Uni-poling with a peak electric field Epk = 0.50 kV/mm (Erms = 0.29 kV/mm), 20 pulse cycles, and a frequency of 2 Hz. These results are discussed in conjunction with polarization–electric field hysteresis and dielectric properties, indicating that pulse-poling treatment is a promising approach to modify the domain structure and piezoelectric properties of BCZT50.
