“…53 For the purpose of decreasing the sintering temperature and increasing the dielectric properties of PZT, low melting additives and high permittivity materials such as lead nickel niobate [Pb(Ni, Nb)O 3 ] (PNN) can be doped into PZT. [54][55][56][57] PNN is a well-known ferroelectric with anomalously large dielectric constant and a broad diffuse phase transition. 58,59 Adding PNN into PZT effectively reduces the PZT Curie temperature while maintaining a high electromechanical coupling factor and a low mechanical quality factor at the morphotrophic phase boundary (MPB).…”

This paper is concerned with direct energy conversion of waste heat into electrical energy by performing the Olsen cycle on lead nickel niobate zirconate titanate (PNNZT) pyroelectric ceramics undergoing a relaxor-ferroelectric phase transition. First, isothermal bipolar displacement vs. electric field hysteresis loops were measured for different temperatures and electric field spans. The Curie temperature varied between 150°C and 240°C as the electric field increased from zero up to 3 MV/m. The energy and power densities of the Olsen cycle on PNNZT were measured by cycling the specimens over a wide range of temperatures, electric fields, and frequencies. A maximum energy density of 1417 J/L/cycle was recorded with 200 μm thick PNNZT cycled at 0.033 Hz between temperatures 20°C and 240°C and electric fields 0.3 MV/m and 9.0 MV/m. To the best of our knowledge, this is the largest energy density ever obtained experimentally for any pyroelectric material. In addition, a maximum power density of 78 W/L was measured by cycling the material temperature between 20°C and 220°C and applying the electric field between 0.3 MV/m and 9.0 MV/m at 0.09 Hz.

“…They are ferroelectric materials that have characteristics such as: high dielectric constant, the temperature at the phase transition point between the ferroelectric and paraelectric phase is broad (the diffuse phase transition), and a strong frequency dependency of the dielectric properties [6,[10][11][12]. The PZT-PZMnN ceramics, as one of PZT-Pb(B′, B″)O 3 solid solutions, received more attention due to their high piezoelectric properties [6,[10][11][12][13][14]. So far, the sintering temperature of PZT-based ceramics is usually too high, approximately 1200°C [9].…”

This chapter presents the investigation of fabrication and the physical properties of the Pb(Zr 1−x Ti x)O 3-Pb(Zn 1/3 Nb 2/3)O 3-Pb(Mn 1/3 Nb 2/3)O 3 multicomponent ceramics. The multicomponent yPb(Zr 1−x Ti x)O 3-(0.925 − y)Pb(Zn 1/3 Nb 2/3)O 3-0.075Pb(Mn 1/3 Nb 2/3)O 3 (PZT-PZN-PMnN) ceramics were synthesized by conventional solid-state reaction method (MO) combined with the B-site oxide mixing technique (BO). Research results show that the electrical properties of PZT-PZN-PMnN ceramics are optimal at a PZT content of 0.8 mol and Zr/Ti ratio of 48/52. At these contents, the ceramics have the following optimal properties: electromechanical coupling factor, k p = 0.62 and k t = 0.51; piezoelectric constant (d 31) of 130 pC/N; mechanical quality factor (Q m) of 1112; dielectric loss (tan δ) of 0.005; high remanent polarization (P r) of 30.4 μC.cm −2 ; and low coercive field (E C) of 6.2 kV. cm −1. Investigation of the domain structure of the two ferroelectric phases (tetragonal and rhombohedral) in the ZnO-doped PZT-PZN-PMnN with compositions at near the morphotropic phase boundary is described as follows: the 90 and 180° domains exist in the tetragonal phase, while the 71, 109, and 90° domains are located in the rhombohedral phase, and the widths of these domains were about 100 nm. Besides, the ceramics exhibited excellent temperature stability, which makes them a promising material for high-intensity ultrasound applications.

“…[7][8][9][10] As demonstrated previously, the addition of ZnO could promote the formation of a liquid phase which expedited mass transfer during a sintering process, resulting in an enhancement of density, grain size as well as electrical properties of ceramics. 11,12 Moreover, ZnO was also used as a substituent for both lead-based solid solution ferroelectric ceramics, that is, Pb(Mg 1/3 Nb 2/3 ) 0.9 Ti 0.1 O 3 , 13 Pb 15 and lead-free ferroelectric ceramics, that is, Bi 0.5 Na 0.5 TiO 3 16,17 and (Na 0.5 K 0.5 )NbO 3 . 18 These results suggested that Zn 2+ ion could substitute a cation located on B-site lattice of the perovskite ceramics, which could in turn change the phase transition temperature and improve the electrical property of those ceramics.…”

Phase formation, microstructures, dielectric, and ferroelectric properties of ZnO‐modified Pb(Mg1/3Nb2/3)0.65Ti0.35O3 (PMNT/xZnO, where x = 0, 0.4, 2.0, 4.0, and 11.0 mol%) ceramics were studied. A coexistence of rhombohedral and tetragonal ferroelectric phases was observed at room temperature in all samples. The ceramics with the relative densities of 93%–95% were prepared. The modification by ZnO led to an increase in grain sizes of PMNT ceramics. The maximum dielectric constant of the pure PMNT ceramic was increased with x = 0.4–4.0 mol% ZnO doping, with the highest value being observed in the 2.0 mol% sample. Both the temperature at which the transition between rhombohedral and tetragonal ferroelectric phases took place (TR‐T) and the Curie temperature of the ceramics tended to increase with increasing x. The ferroelectric properties were enhanced with increased remanent polarization and P(E) loop squareness in the compositions with x = 0.4–4.0 mol%. However, the ferroelectric properties were attenuated with x = 11.0 mol%.
