“…However, the grain size is obviously decreased for x = 0.35 ceramics. This can be attributed to the high‐sintering temperature of BaTiO 3 components, which is agreement with previous literature .…”

This study investigates the effect of poling electric field on polarization alignment, dielectric dispersion, relaxor feature, phase transition temperature (Tm), and piezoelectric properties evolution of (1–x)BiFeO3–xBaTiO3[(1–x)BF–xBT] ceramics with x = 0.26, 0.29, 0.32, and 0.35. The XRD pattern studies indicate that the application electric field induced the polarization alignment along with a significant change of the diffraction intensity of peaks, which gives rise to increasing piezoelectric properties. Simultaneously, the degree of dielectric dispersion and diffuse factor γ in the modified Curie–Weiss equation and Tm increase after applying the poling electric field. Moreover, the relaxor characteristics are more evident with increasing BT content. The dielectric behavior and relaxor feature may be attributed to the small random field domains resulting from local charge imbalance due to off‐valent substituents between A‐ and B‐site cation in (1–x)BF–xBT ceramics. Meanwhile, the application of the poling electric field probably increases the strength of the neighboring dipole–dipole interaction, giving the enhanced degree of dielectric dispersion and Tm.

“…Furthermore, it is easier for BY to distribute well with the increasing sintering temperature.However, Bi is a volatile component at high temperatures. When the sintering temperature is higher than 1420 o C, the decreased densification and increased defects content contribute to the decreased piezoelectric properties [10] . Therefore, both the d 33 and k p decrease with the increase of sintering temperature.…”

Lead-free 0.996(Ba0.85Ca0.15)(Zr0.1Ti0.9)O3-0.004BiYO3 [BCZT-BY] ceramics were prepared by the conventional solid-state sintering method. By means of XRD, SEM, and quasi-static d33 meter etc., the effect of sintering temperature on the microstructure, piezoelectric and dielectric properties of BCZT-BY ceramics were investigated. All the ceramics possess a pure perovskite structure, indicating that Bi3+ and Y3+ are incorporated into Ba0.85Ca0.15Ti0.9Zr0.1O3 lattices to form a solid solution. The results show that the ceramics sintered at 1420°C exhibit the optimum electrical properties: d33 = 130 pC/N, kp = 18.2 %, εr = 4225, and tan δ = 1.95%, respectively.
