“…It is worth mentioning that the piezoelectric properties can be influenced by the microstructures of the ceramics that are associated with the sintering conditions. − In this respect, samples from the 0.52PNN- x PSN-(0.48– x )PT group around the MPB ( x = 0.12–0.16) were chosen for a subsequent microstructure analysis. The selected ceramics possess a dense structure without pores, indicating the grain formation therein during the sintering process (Figures a–c).…”

Ternary/polynary perovskite solid solutions based on binary systems are well-known for their high piezoelectric performance. In this work, a series of Pb(Ni 1/3 Nb 2/3 )O 3 − Pb(Sc 1/2 Nb 1/2 )O 3 −PbTiO 3 compositions with the particularly high piezoelectric coefficient of d 33 * > 1000 pm/V and d 33 > 700 pC/N have been developed. The optimal performance was achieved in the 0.52PNN-0.14PSN-0.34PT composition (d 33 * = 1120 pm/V, d 33 = 804 pC/N, and T m = 109 °C). The high piezoelectric performance of this system is reported and is superior to those of most lead-based ternary/polynary ceramics. By a combination of in situ high-energy synchrotron diffraction with transmission electron microscopy (TEM), the origin of the high piezoelectric response has been unambiguously revealed. Upon application of an external electric field, synchrotron diffraction profiles show no splitting but prominent shifting, indicating that the large intrinsic lattice strain arising from the reduced crystal anisotropy and facilitated polarization variation is associated with the high piezoelectric response. Furthermore, microscopic studies by TEM highlight a heterogeneous ferroelectric domain configuration generated by a small local structural distortion, which is also beneficial for the high piezoelectric performance in the proposed ternary piezoelectric systems. The design process of ternary perovskite solid solutions with a wide morphotropic phase boundary region and small structural distortion may be enlightening for the exploration of other high-performance polynary piezoelectrics.

“…The images revealed that the microstructure densification proceeded with an increase in the PZNN content from 0.1 to 0.25; moreover, the average crystal grain size increased from 0.5 µm to 1.3 µm without the formation of pores [ 28 ]. The increase in grain size was expected to vary with the composition ratio, and the particle growth behavior was anticipated to affect the piezoelectric properties [ 29 , 30 ]. Zheng et al [ 31 ], suggested that the decrease in particle size promotes the enhancement of the internal stress and stabilizes the rhombohedral phase; however, the Figure 1 results indicate the occurrence of a complete phase transition to the rhombohedral phase due to the decrease in particle size at a composition of x = 0.30 [ 32 , 33 ].…”

A multilayer piezoelectric material was fabricated using piezoelectric materials with low-temperature sintering capabilities and high piezoelectric coefficients to develop a functionally superior piezoelectric speaker with a large-displacement deformation. A soft relaxor was utilized to prepare the component materials, with the optimized composition of the investigated piezoelectric ceramics represented by 0.2Pb((Zn0.8Ni0.2)13Nb23)O3−0.8Pb(Zr0.5Ti0.5)O3. Li2CO3 was added to assist the low-temperature sintering conducted at 875 °C, which yielded a multilayer piezoelectric material with superior properties (d33 = 500 pC N−1, kp = 0.63, g33 = 44 mV N−1). A multilayer piezoelectric actuator with a single-layer thickness of ~40 µm and dimensions of 12 × 16 mm2 was fabricated by tape casting the prepared green sheets. Finite element analysis revealed that the use of a PEEK film and a smaller silicone–rubber film as a composite in the diaphragm realized optimal frequency-response characteristics; the vibrations generated by the piezoelectric element were amplified. The optimal structure obtained via simulations was applied to fabricate an actual piezoelectric speaker with dimensions of 20 × 24 × 1 mm3. The actual measurements exhibited a sound pressure level of ~75 dB and a total harmonic distortion ≤15% in the audible frequency range (250–20,000 Hz) at an applied voltage of 5 Vp.

“…In this case, two other factors may thus be responsible for the decrement in the P r value. It has previously been reported that reversal of the polarization process is difficult in smaller grains as compared to larger grains [13,14]. When the grain size decreases, higher polarization discontinuity occurs as the number of grain boundaries increases.…”

Polycrystalline samples of Ba 0.96 Ca 0.04 TiO 3 (BCT) and Ba 0.96 Ca 0.04 Ti 0.96 Mn 0.04 O 3 (BCMT) were synthesized using the solid-state reaction route. XRD analysis confirmed the presence of the tetragonal phase in both as well as an additional hexagonal phase in the BCMT samples. The wt % of the segregated phase was found to be ≈8.96% using Rietveld refinement. SEM micrographs showed an increase in the density and a decrease in the grain size of the BCMT sample. P-E measurements confirmed higher remnant polarization in the BCT samples. A single depressed semicircle was observed in the Nyquist plots indicating non-Debye-type behavior and overlapping contributions of the grains and grain boundaries. The increase in the value of the conductivity exponent "n" (and n < 1) with temperature suggested that the electrical conduction mechanism was non-overlapping small polaron tunneling. The electron acceptor nature of the Mn ions and lower grain size of the BCMT samples resulted in higher activation energy as compared to the BCT samples.
