Highly textured (1–x)Pb(Mg1/3Nb2/3)O3‐xPbTiO3 (PMN–xPT) piezoelectric ceramics were fabricated. It was found that [001] textured rhombohedral PMN–24%PT ceramic exhibited a quasi‐linear piezoelectric strain behavior with low hysteresis. The strain hysteresis of PMN–24%PT ceramic was reduced from 22.5% to 9% at 30 kV/cm using the texture method. Accurate displacement was generated by DC field using textured PMN–24%PT ceramic. The domain configurations in textured PMN–xPT ceramics were figured out using the chemical etching method. It was demonstrated that the quasi‐linear and low‐hysteretic strain behavior was due to a fixed domain configuration. We predict that the textured PMN–24%PT ceramic will facilitate the development of low‐voltage driving piezoelectric actuators with high precision.

“…This is related to a low coercive field of E c ∼ 8.7 kV/cm of undoped random samples, as shown in Figure S3. The coercive field is known to be an important factor affecting the electrical field stability of piezoelectric materials and a higher E c value is preferred to favor the strong fatigue resistance. , Textured-2BT samples can exhibit better fatigue resistance behavior in comparison with the doped random counterpart in both low and high electric field amplitude conditions (Figure c,f).…”

“…The stability of piezoelectric properties under an external electric field is the most essential factor in determining their transition to practical applications. Polarization fatigue is defined as the continuous loss of switchable polarization under a cyclic electric field and has been extensively investigated in bulk polycrystalline Pb(Zr,Ti)O 3 -based ceramics. − The common mechanisms driving the electric fatigue in bulk ceramics include the electrode–ceramic interface effects, domain wall pinning by charged defect accumulation, occurrence of microcracks due to residual strain, and diffusion of electrode metal to the grain boundaries. − Apart from these mechanisms, piezoelectric single crystals and thin films have shown additional fatigue features related to material anisotropy. − Specifically in Pb(In 1/2 Nb 1/2 )O 3 –Pb(Mg 1/3 Nb 2/3 )O 3 –PbTiO 3 (PIN–PMN–PT) single crystals, the polarization degradation was found to occur after 50–100 bipolar cycles in the ⟨110⟩ direction, while the ⟨001⟩ oriented counterpart exhibited almost fatigue-free characteristics until 10 4 cycles . The fatigue-resistant behavior of ⟨001⟩ oriented crystals in comparison with ⟨110⟩ oriented counterparts is mostly related to relatively smaller domain size .…”

In conjunction with ultrahigh d 33 and Q m , the electrical fatigue behavior of high-power piezoelectric ceramics is highly relevant for practical applications. In this study, a comparative study of fatigue behavior between randomly oriented and ⟨001⟩ textured ceramics is investigated. It is found that ⟨001⟩ textured ceramics exhibit better fatigue resistance behavior in comparison with the random counterpart. The superior fatigue resistance of textured ceramics originates from its smaller domain size with high domain wall density, favorable domain wall switching, and internal stress relaxation during the electric field cycling process. Both mechanical damage and domain wall pinning mechanisms are found to play an important role in influencing the fatigue behavior of high-power textured ceramics. Detailed microstructural analysis along with electrical fatigue measurement under bipolar and unipolar modes is conducted to confirm the mechanisms controlling the degradation as a function of varying fields and temperatures. High-resolution electron microscopy results demonstrate that BaTiO 3 (BT) templates present within the textured ceramics do not induce mechanical damage during electric field cycling.

“…13 The PIN-PMN-PT ternary ferroelectrics have been intensively studied due to their higher phase transition temperature (T R-T > 110 • C) and higher E c (>5 kV/cm) with piezoelectric properties comparable to PMN-PT crystals. 14 Although relaxor ferroelectric single crystals have outstanding piezoelectric properties, their applications in piezoelectric devices are challenged by high cost, low yield, small size, composition inhomogeneity, and difficulty of fabricating net-shape (odd or conformal) components. Alternatively, templated grain growth (TGG) method is a cost-effective way to obtain high-performance grainoriented or textured ceramics.…”

Design of a projecting‐receiving dual‐purpose transducer is challenging due to the difficulty of synthesizing piezoelectric materials with combinatory “soft” properties (high piezoelectric coefficient d) and “hard” properties (low dielectric loss and high mechanical quality factor Qm). In this study, we provide a different perspective to address this challenge via exploiting single‐crystal‐like electrostriction coefficient Q33 through the fabrication of grain oriented or textured “hard” piezoelectric ceramics. Mn‐doped 0.27Pb(In1/2Nb1/2)O3–0.41Pb(Mg1/3Nb2/3)O3–0.32PbTiO3 (Mn:PIN–PMN–PT) piezoelectric ceramics with a high [0 0 1]c texture fraction of 99% were synthesized, which exhibit three times greater piezoelectric properties (d33 ∼ 828 pC/N) than random counterparts (d33 ∼ 251 pC/N), while maintaining low loss (tan δ ∼ 0.5%, Qm = 443). According to the formula , the large improvement of d33 in textured ceramics is mainly due to a doubling increase in dielectric constant ε33 and Q33 (∼0.057 m4/C2). Notably, the Q33 exhibits remarkable similarity to that of PMN–PT single crystals, further contributing to the enhanced piezoelectric performance of textured ceramics. Phase field model of ferroelectrics was performed to understand the texturing on Q33 and elucidate the underlying mechanism at the domain level. The textured ceramics exhibit excellent combinatory “soft” and “hard” properties, which are the promising materials for developing projecting‐receiving dual‐purpose transducers with high efficiency and high sensitivity.
