After decades of study and development, piezoelectric materials have been used in various applications. Piezoelectric material is highly acknowledged as one of the primary functional materials in precision and acoustic engineering fields. Researchers are being pushed to explore novel materials and device combinations for new applications due to increasing demand, notably from the electrical, energy, and biomedical sectors. On the other hand, engineers are always working to enhance existing technology. Since the field has such a broad reach, it is vital to present an overview of the many areas of piezoelectric materials. This chapter focuses on the fabrication of different piezoelectric materials, applications, and challenges.

“…12) Qiu et al prepared cubic PZT particle from Pb(NO 3 ) 2 , ZrOCl 2 •8H 2 O, and TiCl 4 , with NaOH as the mineralizer. 13) Although different precursor sources to synthesize PZT particles have been reported, high concentrations of KOH or NaOH were used as the mineralizer. Tetramethylammonium hydroxide (TMAH) has been reported as a promising mineralizer for hydrothermal method because it can prevent the contamination by alkalis and/or halides.…”

Cubical Pb(Zr,Ti)O 3 (PZT) crystals (PZT cubes) were synthesized using a hydrothermal method at different synthesis temperatures from 140 to 220°C. The Pb(Zr 0.52 Ti 0.48)O 3 precursor solution was prepared from Pb(CH 3 COO) 2 •3H 2 O, Zr(OH)[(OCH(CH 3)COO ¹ ] 3 (NH 4 +) 3 , and titanium (IV) bis(ammonium lactato)dihydroxide. In this study, the effects of synthesis temperature on the shape, morphology, and crystallinity of PZT crystals were investigated. We successfully obtained PZT cubes possessing faceted structures without circular shaped PX-phase (Ti-rich PZT) at a synthesis temperature of 180°C; these PZT cubes consisted of perovskite phase without any non-ferroelectric pyrochlore phase. Precise analysis based on selected area electron diffraction and energy-dispersive X-ray spectroscopy revealed that PZT cube was a single crystal and the chemical composition of PZT cubes was closed to the nominal composition of the PZT precursor solution, respectively. PZT cubes with single perovskite phase could be synthesized at a lower temperature of 180°C by the hydrothermal method, compared with conventional methods such as solgel process and metal organic decomposition method. The piezoelectric properties were confirmed for single PZT cubes using the piezoresponse force microscopy mode of a scanning probe microscope.

“…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.
