“…The double P – E hysteresis loop, which was previously observed in the acceptor‐doped PZT‐based ceramics and the MnO 2 ‐doped (K,Li)(Nb,Ta)O 3 and BaTiO 3 ceramics, has been attributed to the P d formed between acceptor ions and oxygen vacancies . Moreover, the double P – E hysteresis loop formed in the CuO‐added N 0.5 K 0.5 N ceramic was explained by the P d formed between Cu 2+ ions and oxygen vacancies .…”

In this study, 1.0 mol% CuO-added (Na x K 1 -x )NbO 3 (CN x K 1 -xN) ceramics with 0.0 ≤ x ≤ 0.5 were sintered at a relatively low temperature of 960°C. A large Q m value (≥1750) was obtained for the specimens with x ≤ 0.2 owing to the hardening effect of Cu 2+ ions, indicating that a large number of Cu 2+ ions had replaced Nb 5+ ions in these ceramics. The double polarization versus electric field (P-E) hysteresis loop was observed for the specimens with x ≤ 0.2, and was explained by the defect polarization (P d ) formed between Cu 2+ ions and O 2 -vacancies. These specimens also exhibited a sprout-shaped strain versus electric field (S-E) curves with a large strain of 0.14%-0.15% at 8.0 kV/mm because of the internal bias field produced by P d . For the CN 0.2 K 0.8 N ceramic, a double P-E hysteresis loop was maintained at 125°C without remnant polarization. Moreover, this ceramic showed a large strain of 0.175% after 10 4 cycles when a high electric field of 8.0 kV/mm was continuously applied to the specimens during each cycles. Therefore, CN 0.2 K 0.8 N is a useful lead-free piezoelectric ceramic for multilayer actuators.

“…[1][2][3][4][5]. The properties of PZT-type ceramics depend on the ratio of Zr 4+ /Ti 4+ and on the admixtures introduced to the base composition [6][7][8][9][10]11]. In the room temperature pure PZT has ferroelectric properties (so it possesses also piezo and pyroelectric properties) for: 0.042<x<0.380 (rhombohedral phase R3c), 0.380<x<0.470 (rhombohedral phase R3m) as well as 0.480<x<1.000 (tetragonal phase P4mm) [5,12].…”

In paper three multicomponent PZT-type ceramics doped by Mn4+, Sb3+, Dy3+, W6+ have been prepared by the conventional mixed oxide method. The multicomponent PZT-type ceramic powders were synthetized by calcining route, while densification was carried out by pressureless sintering method. The paper presents XRD, SEM, EDS, dielectric and DC electric conductivity measurements of the multicomponent PZT-type ceramic samples. Conducted tests indicate obtained multicomponent PZT-type exhibit good dielectric properties giving the possibility for their use as actuators and piezoelectric transducers in modern micromechatronic and microelectronic applications.

Tunable Pyroelectricity around the Ferroelectric/Antiferroelectric Transition

et al. 2017

The pyroelectric performance of Pb0.99Nb0.02[(Zr0.57Sn0.43)0.92Ti0.08]0.98O3 ceramics was quantified by dielectric, polarization, and specific heat capacity measurements. The tunability of pyroelectric properties upon electric field application was studied as a function of temperature. The large pyroelectric coefficient of 0.28 C m−2 K−1 was associated with the ferroelectric (FE)–antiferroelectric (AFE) phase transition. The pyroelectric coefficient can be tuned over a broad temperature range of almost 40 K above the zero electric field phase transition. Electrical and thermal measurements were used to estimate various pyroelectric figures of merit. Pyroelectric figures of merit are almost three order of magnitude higher than those previously reported in FE materials. The large pyroelectric properties indicate that the investigated material is a promising candidate for many pyroelectric applications.
