“…Since the discovery of PZT, many researchers have reported a three-component system including relaxor ferroelectric materials based on PZT, such as Pb(Zn 1/3 Nb 2/3 )O 3 –Pb(Zr,Ti)O 3 (PZN-PZT) [ 9 ], Pb(Mn 1/3 Nb 2/3 )O 3 –Pb(Zr,Ti)O 3 (PMN-PZT) [ 10 ], Pb(Fe 1/2 Nb 1/2 ) O 3 –Pb(Zr,Ti)O 3 (PFN-PZT) [ 11 ], and Pb(Sb 1/2 Nb 1/2 )O 3 –Pb(Zr,Ti)O 3 (PSN-PZT) [ 12 ], allowing the piezoelectric characteristics to be changed in various ways based on the material’s purpose. However, these three-component piezoelectric ceramic compositions generally have low dielectric constant and mechanical quality factor, which limits their applications to energy conversion devices, so research on compositions, such as four-component systems, have been actively conducted.…”

To achieve good long-term temperature stability in devices used in energy-conversion applications, this study is aimed at developing combined ceramics, referred to as PZN-PMN-PZT, comprising Pb(Zn1/3Nb2/3)O3 (PZN) and Pb(Mn1/3Nb2/3)O3 (PMN), which are typical relaxor ferroelectric materials, and Pb(Zr,Ti)O3 (PZT). The piezoelectric properties were compared based on several parameters according to the change in the composition ratio between relaxor materials, amounts of Sb2O3 dopant, and Zr/Ti ratio in the PZT system. Finally, we established optimal poling conditions to improve the electrical properties of the optimized piezoelectric material, based on the evaluation of ceramic properties according to the applied voltage during the poling process. The optimized composition of the investigated piezoelectric ceramics is represented by 0.14PZN-0.06PMN-0.80PbZr0.49Ti0.51 + 0.3 wt.% CuO + 0.3 wt.% Fe2O3 with 0.1 wt.% Sb2O3 doping, which yielded the superior properties (d33 = 361 pC/N, Qm = 1234, Tc = 306 °C).

Tape ceramics are widely used in the sensor and electronic industries. In this work, we studied the ferroelectric properties of the 0.975Pb(Zr0.52Ti0.48)O3-0.025Sr(K0.25Nb0.75)O3 tape ceramic; (PZT-SKN). We fabricated the PZT-SKN using doctor blade technique with the slurry, obtained from the calcined of PZT-SKN mixing with organic solution. The crystalline structure was investigated by using X-ray diffraction, relative density, and Vickers Hardness technique. We also determined the dielectric properties and polarization electric field loops. The results of crystalline structure show that the percentage of perovskite is 97.57 %, the relative density is 98.4 %, and Vickers Hardness is 107 MPa. At the thickness 0.89 mm, the dielectric constant temperature is 1499 at 532 °C, the remnant polarization is 17 μC cm−2, Currie temperature is 552 °C, and piezoelectric coefficient is 235 pC N−1. The PZT-SKN tape ceramic has the ferroelectric properties better than tablet ceramic.
