“…In addition, the values of d 33 of the PZT ceramics have been reported to increase consistently with increasing grain size up to 3 μm, which is related to the domain wall motion [15]. Similarly, d 33 increased consistently with grain size up to 6 μm in BFO-BT systems [16,17]. Thus the piezoelectric properties in our case also might be directly related to the grain size.…”

Three types of green compacts were formed by using applied loads of 1, 2, and 3 ton, respectively, and were sintered at 980 • C. The sintered ceramics with an applied load of 1 ton had the highest volume shrinkage, but the density was almost similar for all ceramics. There was no change in the crystal structure for all ceramics. The piezoelectric and the ferroelectric properties of the ceramics showed that the ceramic with an applied load of 1 ton had the best direct piezoelectric coefficient (d33) and the largest remnant polarization. The microstructure indicated that the ceramics with an applied load of 1 ton had an average grain size of 6 μm. The results suggest that the piezoelectric property could be directly related to the grain size.

“…When x ≥ 0.32, the phase structure converted to pseudocubic phase. The rhombohedral and the pseudocube phase coexist when x is around 0.3, the existence of MPB in 0.7BF-0.3BT-BZT sample [25,27,37]. ceramics is relatively larger.…”

The structure, microstructure, piezoelectric properties, ferroelectric properties and Curie temperature of (1x )BiFeO 3 -x BaTiO 3 -Bi(Zn 0.5 Ti 0.5 )O 3 +MnO 2 +Li 2 CO 3 ceramics were investigated experimentally by improved solid-state reaction approach. The crystalline structures were examined by X-ray diffractometry. When x = 0.3, the rhombohedral and pseudocubic phases coexist in the ceramic structure. It is considered that the morphotropic phase boundary was formed here. At the same time, the piezoelectric performance d 33 , Curie temperature T C , and depolarization temperature are as high as 184 pC/N, 550°C, 530°C at x = 0.3, respectively. It is worth noting that when x = 0.24, the ceramics have a high T C = 580°C and low dielectric loss tan δ = 1.9%. These results show that the BFBT-BZT system ceramics are applicable ceramics with high piezoelectric properties in high temperature elds.

“…Unfortunately, these ceramics generally exhibit poor temperature stability induced by the low T d (70-300 1C), T C and/or the room-temperature coexistence of tetragonal and orthorhombic phases. Compared with the above materials, BFO-based ceramics [58][59][60][61] are more attractive candidates for being the high-temperature piezoelectric ceramics due to their super high T C /T d and large d 33 . It can be seen that the BFO-based ceramics simultaneously show high d 33 (136-163 pC N À1 ) and high T C /T d (428-485 1C/380-425 1C).…”
