Effect of sintering temperature on the electrical properties of pristine BF-35BT piezoelectric ceramics

In this study, 0.65Bi1.05FeO3–0.35BaTiO3 (BF-35BT) lead-free piezoelectric ceramics were prepared using a conventional solid-state method to determine the effects of sintering temperature on their microstructures and electrical properties. The average grain size increased with sintering temperature, but not significantly, and the relative density of the ceramics increased and then decreased at high sintering temperatures due to the...
