This article studies the microstructure and piezoelectric properties of low sintering temperature lead-free ceramics [Formula: see text]-doped with ZnO nanoparticles (noted as 0.48BZT-y, y is content of ZnO in wt%, y =0.00, 0.05, 0.10, 0.15, 0.20 and 0.25). The obtained results of Raman scattering and dielectric measurements have confirmed that [Formula: see text] has occupied B site, to cause a deformation in the ABO3-type lattice of the 0.48BZT-y compounds. The 0.15 wt% ZnO-doped ceramic sintered at 1350[Formula: see text]C exhibited excellent piezoelectric parameters: [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text]. The obtained results indicate that the high-quality lead-free BZT–BCT ceramic could be successfully synthesized at a low sintering temperature of 1350[Formula: see text]C by doping an appropriated amount of ZnO.

Low Sintering Temperature

High-quality piezoelectric ( Ba 0.85 Ca 0.15)( Zr 0.1 Ti 0.9) O 3 thick films with dense and homogenous microstructures were fabricated at a low sintering temperature (900°C) using a CuBi 2 O 4 sintering aid. The 10 μm thick film exhibited a high longitudinal piezoelectric constant d33, eff of 210 pC/N with estimated unconstrained d33 value of 560 pC/N very close to that in the corresponding bulks. Such excellent piezoelectric effect in the low-temperature sintered ( Ba 0.85 Ca 0.15)( Zr 0.1 Ti 0.9) O 3 thick films is comparable to the case of lead-based PZT thick films, and may be a promising application in lead-free microdevices such as piezoelectric microelectromechanical systems (MEMS).

Factors Affecting

Lead-free piezoelectric ceramic 0.48Ba[Zr0.2Ti0.8]O3 - 0.52[Ba0.7Ca0.3]TiO3 (BZT-BCT) with a nanostructure was manufactured by traditional ceramic technology. Nanostructure and the sintering aid reduce the calcinating temperature as well as the sintering temperature and some electrical properties of BZT-BCT ceramics systems are researched. The results show that they can reduce the calcinating and sintering temperatures of ceramics systems from 1250 0C and 1450 0C to 1170 0C and 1350 0C. Moreover, the piezoelectric properties of the 0.48BZT - 0.52BCT at the optimal calcinating and sintering temperature will be discussed in detail.

(Ba[Formula: see text]Ca[Formula: see text])(Zr[Formula: see text]Ti[Formula: see text])O3 (BCZT) lead-free ferroelectric ceramics were prepared at low sintering temperature via a hydrothermal route. The hydrothermal-synthesized BCZT precursor powder presents phase-pure perovskite structure and rather homogenous particles with dozens nanometers, which provides high sintering activity. Pure perovskite BCZT ceramics are synthesized at rather low sintering temperature accompanied by rather uniform microstructure morphology and high relative density. Dielectric peaks of the BCZT ceramics are rather broad, and their dielectric response behavior combines the characteristics of both the normal and relaxor ferroelectrics. The BCZT ceramics exhibit excellent ferroelectricity and promising electric energy density, which can be enhanced further with increasing electric field.
