| Abstract: | In this study, the creep and fatigue characterization is performed for 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3(BZT-BCT) bulk ferroelectric ceramics. A function generator is used to generate the required waveform of the voltage amplifier for fatigue and creep analysis. The evolution of polarization is studied for electrical creep. The effects of temperature and electric field on the electric displacement are studied. Hysteresis butterfly loops are analyzed for fatigue tests for different thermal loads up to 106 cycles. It inheres that the material is stable below 75°C and can withstand high cycle fatigue loads (25 Hz, ± 1.5 kV/mm). © 2021 World Scientific Publishing Co. Pte Ltd. All rights reserved. |
