In this work, screen-printed thick films of PFN–30BFO were prepared on gold-coated alumina substrates and sintered at 800 °C, 850 °C and 930 °C. The impact of the sintering temperature on their properties was studied. The films annealed at 930 °C exhibited excessive electrical conductivity. In contrast, well developed polarization versus electric field hysteresis loops were observed in the films treated at 800 °C and 850 °C. The films annealed at 800 °C had the smallest grain size and dielectric permittivity values but achieved the highest dielectric breakdown strength. The findings of this study highlight the potential of PFN–30BFO screen-printed films, sintered at 800 °C, for use in miniaturized high-voltage electronic devices.Elsevier20262026-04-17 15:26:48Neznano29038Nizozemskasl
