“…However, these systems are prepared by the conventional mixed oxide method or columbite precursor method, and only their microstructures, dielectric properties and piezoelectric properties were studied [12][13][14][15][16]. Other than these methods mentioned, the B-site oxide precursor method should be another promising technology to enhance the solid-state reaction.…”

“…Attempts to synthesize polycrystalline PZN at ambient pressure generally result in partial decomposition and the formation of one or more cubic pyrochlore phases. 4,5 Similar problems have been found in the sintering of polycrystalline Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 ceramics (PMN-PT) where pyrochlores with a wide compositional range were observed 6 although unlike PZN-PT, methods for fabricating PMN-PT polycrystalline ceramics have been found. 7 The pyrochlores formed during PZN-PT synthesis are nonferroelectric, and even the smallest quantity of another phase degrades the piezoelectric properties of the parent perovskite.…”

“…The utility of the material in piezoelectric applications would be greatly enhanced if polycrystalline ceramics were available; however, the ease with which the single crystals have been grown has not been mirrored in the synthesis of polycrystalline PZN or PZN–PT, most likely due to the very same thermal instability.

The thermal stability of the relaxor ferroelectric Pb(Zn1/3Nb2/3)O3 (PZN) upon heating was studied using high‐temperature X‐ray diffraction (XRD) and scanning electron microscopy. It was found that single‐phase PZN is stable below 700°C, whereupon the first decomposition phase, the pyrochlore Pb1.83 Nb1.71Zn0.29O6.39 was observed. With the increasing temperature, the amount of pyrochlore increased until at 1100°C there is no PZN remaining. Pyrochlore formation was accompanied by the precipitation of ZnO above 800°C and after holding at 1100°C, the formation of Nb2ZnO6. Rietveld refinements based on the XRD patterns have allowed the relative phase proportions as well as the atomic site occupancies of the metal ions in PZN and the pyrochlore to be estimated. The Zn site occupancy within the perovskite PZN decreases upon heating in parallel with the pyrochlore formation. An elemental mass balance based on the XRD results shows that PZN decomposition is well under way before any Pb is lost from the sample. This indicates that Zn egress rather than Pb volatility is the determining factor in the instability of PZN, contrary to prior published work.

“…The values obtained for the physical and electrical properties depend on the method of obtaining these materials. The most often used procedures used for the development of intelligent materials are conventional mixed oxides technique [4,5], B-oxides technique [6], two-step columbite method [7], sintering by hot pressing [8] and a relatively new technique spark plasma sintering (SPS) [9], etc. Compositions from complex systems based on lead titanate-zirconate solid solutions are conventionally sintered at high temperatures (higher than 1150 o C) for more than 1 hour.…”

In this paper B-oxide sintering process and Spark plasma Sintering (SPS) method is used to synthesize 0.88Pb(Zr0.52Ti0.48)O3 – 0.12Pb(Mn1/3Sb2/3)O3 – x at%Pr complex system where x = 0 and 0.02. The sintering temperature used in the SPS technique is considerably lower than that used in the B-oxide method (200 to 400oC) with significant decrease of the duration of the sintering route, arriving to some minutes instead of some hours. The aim of the study is the investigation of the effect of sintering technique on the dielectric and ferroelectric properties of such piezoelectric materials. The properties of the developed ceramic materials were determined: the development of crystalline phases was investigated by X-ray diffraction technique and the microstructural behavior by scanning electron microscopy was observed. The composition obtained by the SPS technique shows a lower remnant polarization and maximum strain, as well as a higher coercive field, compared to the those obtained using the same composition produced by B-oxide method.
