“…This is due to the volatilization of PbO at elevated temperatures, which often causes deviation from stoichiometry, inhomogeneous microstructure and porosity [20,21] and a high tetragonality (c/a = 1.064 with c = 0.4156 nm and a = 0.3902 nm [22]) that develops during cooling across the Curie point, which induces large internal stresses in the unit cell that can easily result in flaws and cracks. Sintering at low temperatures (600°C-800°C) results in the grain size of 0.7±0.2 µm, which increases to 2.7±0.6 µm when sintered at high temperature (900°C), which is illustrated in Figure 1a.…”

There have been a large number of papers on bismuth ferrite (BiFeO 3 ) over the past few years, trying to exploit its room-temperature magnetoelectric multiferroic properties.Although these are attractive, BiFeO 3 is not the ideal multiferroic, due to weak magnetization and the difficulty in limiting leakage currents. Thus there is an ongoing search for alternatives, including such materials as gallium ferrite (GaFeO 3 ). In the present work we report a comprehensive study of the perovskite PbTi 1-x Pd x O 3 with 0 < x < 0.3. Our study includes dielectric, impedance and magnetization measurements, conductivity analysis and study of crystallographic phases present in the samples with special attention paid to minor phases, identified as PdO, PbPdO 2 , and Pd 3 Pb. The work is remarkable in two ways: Pd is difficult to substitute into ABO 3 perovskite oxides (where it might be useful for catalysis), and Pd is magnetic under only unusual conditions (under strain or internal electric fields).The new material, as a PZT derivative, is expected to have much stronger piezoelectric properties than BiFeO 3 .

“…Yoon et al showed that ZnO could enhance the piezoelectric voltage output coefficient (g 33 ) and piezoelectric charge constant (d 33 ) [16], Wang et al reported that the ZnO nanowhisker could greatly improve the piezoelectric properties, mechanical strength and aging rate of PZT ceramics [17], and Zhao found the similar results from nano ZnO doping into the PZT thick-film by a hybrid sol-gel route [18]. Wongmaneerung et al also showed that the suitable addition of ZnO nanowhiskers into PT ceramics could enhance the densification, mechanical and dielectric properties [19]. Similarly to lead-free piezoelectric ceramics, the nano ZnO addition had the same effects in enhancing the d 33 , k p and electric properties at a lower sintering temperature (<1070 • C) [20,21].…”

“…To improve the dielectric properties of ferroelectric ceramics, nanocomposites consisting of two or more materials with different macroscopic properties are more attractive than their single-phase counterparts. Lead titanate (PT) ceramic-based composites have recently been developed to improve the mechanical and dielectric properties [3][4][5]. In our previous work [4,5], silicon carbide (SiC) nanofibers and zinc oxide (ZnO) nanowhiskers were employed as the reinforcement in the composites because of their ability to resist crack growth.…”

Nanosized zinc oxide/lead titanate (ZnO/PT) ceramic matrix nanocomposites have been studied. Under an appropriate sintering condition, ZnO/PT ceramic nanocomposites were successfully fabricated by a pressureless sintering technique. Thermal expansion and polatization behaviors were determined by using the dilatometer. This technique measures the temperature-dependent of the strain, and the magnitude of polarization can be deduced from the sets of the thermal expansion data. The calculated electric polarization values on the ZnO/PT nanocomposite ceramics show the simple approach to determine the temperature dependence of the polarization below and around the transition temperature. Various aspects on understanding the polarization behavior and other effects in the ferroelectric are discussed.
