Summary: Hard piezoelectric properties were investigated in lead-free BiFeO3-BaTiO3 (BF- BT) ceramics. Rhombohedral (R) phase ceramics of (1 - x)BF-xBT (x = 0.20-0.30) were prepared. The x = 0.20 ceramic showed the best hard piezoelectric properties, with the highest Q(m) = 403 and the highest T-C = 607°C. In contrast, the x = 0.30 ceramic showed soft piezoelectric properties, with d(3)(3) = 301 pC/N and k(p) = 0.33, and T-C = 510°C. The BF-BT system in the R-phase-rich region has good hard piezoelectric properties for transducer applications.

Summary: This study investigated the effects of Bi2O3 doping on the low-temperature sintering properties of PZT-5H ceramic powder. It was found that when the mass fraction of Bi2O3 is 0.9%, PZT-5H ceramics can be completely sintered at 850 degrees C. The chemical composition at this doping level exhibited the best electrical properties and was located at the morphological phase boundary (MPB). A multilayer piezoelectric ceramic actuator was also created to demonstrate the real-world applications of using this material in low-temperature co-fired devices.

Summary: C-doping in ZnO was achieved through a facile and speedy SPS technique, improving electrical conductivity and power factor by reducing band gap and increasing carrier concentration. Meanwhile, introduced point defects strengthened phonon scattering and decreased thermal conductivity, leading to a peak ZT value of 0.024 at 773 K for Zn(O,C) bulk. This demonstrates that C-doping in ZnO is an effective and convenient strategy to enhance thermoelectric performance.

Summary: By replacing Fe3+ with Ga3+ in the BFGax-BT system, the mechanism of leakage current shifts from space charge limited conduction to Ohmic conduction and Schottky emission, resulting in a ceramic with a good combination of piezoelectric properties (d(33) = 174 pC N-1 and k(p) = 29%) and high Curie temperature (T-C = 497 degrees C). This study provides insights for preparing high insulation and high piezoelectric performance BF-BT-based ceramics by suppressing the valence change of Fe3+ and the appearance of V O center dot center dot.

Summary: This paper reports the enhanced high-temperature piezoelectric properties of Bi(Zn0.5Ti0.5)O-3-modified BiFeO3-BaTiO3 ceramics prepared using a two-step sintering method. The addition of BZT inhibits grain growth, reduces leakage current, and induces a ferroelectric to relaxor transition. The optimized piezoelectric properties were achieved at x = 0.01 composition, with d(33) = 193 pC N-1, P-r = 20.6 μC cm(-2), T-C = 503 °C, and k(p) = 36%, due to the synergistic effect of an appropriate C-R/C-PC ratio, improved insulation, and good polarization performance. These findings demonstrate the potential application of lead-free piezoceramics at high temperatures.
