“…It was reported that the pure PZT phase could be formed at the KOH concentration of 1⋅6~2⋅1 M (Wang et al 2004). But pure PZT phase is obtained at NaOH concentration of 1⋅2 M, 200~230°C and Pb/(Zr, Ti) > 1⋅5 in the present study.…”

“…At this temperature, PbO volatility deteriorates the ceramic properties. Therefore, several methods have been developed to reduce the sintering temperature at which the ferroelectric PZT phase crystallizes, such as high energy ball-milling (Lee et al 2007), sol-gel method (Faheem and Shoaib 2006;Linardos et al 2006;Tahar et al 2007;Sangsubun et al 2008), hydrothermal method (Traianidis et al 2000;Deng et al 2003;Euphrasie et al 2003;Piticescua et al 2004;Wang et al 2004;Ahn et al 2006;Ko et al 2007;Yang et al 2007;Dunn 2008) and wet chemical method (Sahoo et al 2006). Hydrothermal synthesis is one of the most important tools for advanced material processing at low temperature (Byrappa and Adschiri 2007).…”

“…Hydrothermal synthesis is one of the most important tools for advanced material processing at low temperature (Byrappa and Adschiri 2007). It was used for preparing PZT powders (Deng et al 2003;Piticescua et al 2004;Wang et al 2004;Dunn 2008), films (Euphrasie et al 2003;Ahn et al 2006;Ko et al 2007) and even nanowhiskers from different precursor feedstocks. The desirable products can be synthesized by controlling the experimental parameters such as alkalinity, reagent, mineralizer, hydrothermal treatment temperature and time.…”

Pb(Zr 0⋅52 Ti 0⋅48 )O 3 (PZT) powders were prepared by hydrothermal method. The effects of experimental parameters, including Pb/(Zr, Ti) ratio, alkaline concentration, reaction temperature and time on the product powders were studied in detail. Pure PZT powders were synthesized at suitable experimental conditions and Raman spectra confirmed the PZT with a perovskite-type structure. The homogeneous PZT powders with cubic-shaped morphology were formed at alkaline concentration of 1⋅2 M after reacting at 230°C for 2 h. The pure PZT powders obtained at low temperature and low alkaline concentration were attributed to precursors, TiCl 4 , with high activity and mineralizer NaOH with small cation radius.

“…Alternatively, highly active TiCl 3 were selected as the precursor, and fine PZT particles were prepared at a low temperature of 110°C [14,15]. It's found that previous reports were mainly focused on the powder processing, especially concerning the size reduction and yielding efficiency [13,16,17], while the work dealt with subsequent PZT ceramic preparation and piezoelectricity was limited. Thus, in the present work, great efforts were paid toward the sinterability and piezoelectric properties of hydrothermally synthesized PZT powders.…”

In this work, Pb(Zr, Ti)O 3 (PZT) powders were prepared by traditional hydrothermal method and solid state reaction. Subsequently, PZT ceramics were sintered and their electric properties (including piezoelectric coefficient d 33 , electromechanical coupling coefficient k p and mechanical quality factor Q m ) as a function of sintering temperature (1125-1250°C) were comparably studied. Given that the Pb deficiency may exist in the hydrothermally synthesized PZT powders, effects of Pb excess (0, 20 and 80 mol%) in the hydrothermal precursor on their sinterability were also involved. The hydrothermally synthesized PZT powders with 80 mol% Pb excess showed the highest sintering activity, and their electric properties peaked at 1175°C (d 33 = 225 pC/N, k p = 0.446, Q m = 300). It's demonstrated that A-site deficiency may degrade the sintering activity of PZT powders, and hydrothermal synthesis of PZT powders with appropriate Pb excess was the compromising pathway to increase their sinterability, decrease the sintering temperature and lessen the volatilization of Pb ion in the fabrication of widely applied PZT ceramic.

“…PZT compositions can be obtained by wet chemical methods like sol-gel, co-precipitation, hydrothermal etc. and dry methods like solid state route [15][16][17] or mechanical activation (MA) processes 18 for nano crystalline ceramics. Mechanical activation process employees high energy ball mill (HEBM) in which raw material powders are milled intimately by tungsten carbide balls.…”

Synthesis by mechanochemical activation route and optimisation for power harvesting properties of nano-structured Pb0.98La0.02(NiSb)0.05[(Zr0.52Ti0.48)0.995]0.95O3 [La-PNS-PZT] ferroelectric ceramic composition has been carried out and reported here for the first time. Progressive perovskite phase formation during mechanical activation from 5 h to 40 h followed by reactive sintering was analyzed from X-Ray Diffraction analysis. Noticeable formation of perovskite phase after10 h of milling and further its completion in successive reactive sintering was observed. Particle morphology of the 10 h activated nano-La-PNS-PZT powder analysed by High Resolution Transmission Electron Microscope (HRTEM) indicated average particle size (d50) of about 24nm. Microstructural studies of samples reactively sintered at 1220 °C were performed by Field Emission Scanning Electron Microscopy (FESEM) for powders activated for various durations, indicated the compact microstructure for 10 h activation which resulted in optimum piezoelectric properties viz. piezoelectric charge coefficient (d33=449x10-12 C/N), piezoelectric voltage coefficient (g33= 32x10-3 m-V/N), Figure of merit for power harvesting (14.4 x10-12 V-m-C/N2) accompanied by excellent stability of permittivity in the range -50 °C to 100 °C. The output voltage obtained from simulated random vibrations of aerospace vehicles at various Power Spectrum Density (PSD) values, measures about 3.0 mV output across resistance of 1 kΩ indicating suitability of composition for harvesting the power from aerospace vehicle vibrations.
