AbstractThe microstructure and electrical properties of 3-0 type composite of Na0.5Bi2.5Nb2O9-based bismuth layered piezoceramics modified by Al2O3addition are investigated. The darker and plate-like grains, locating at the grain boundaries, are confirmed to be pure α-Al2O3by high resolution transmission electron microscope, not a Bi2AlNbO7pyrochlore phase. This 3-0 type Na0.5Bi2.5Nb2O9-Al2O3composite piezoceramics have a large piezoelectric constant d33of 15.2pC/N with good temperature stability up to 600 °C, and good ferroelectric properties with a relatively large remnant polarization of ~11.6 μC/cm2. These demonstrate that designing a 3-0 type composite structure would be an effective approach to tailor the microstructure and improve the electrical properties of bismuth layered piezoceremics for their potential applications at temperature up to 600 °C. © 2017 Elsevier Ltd and Techna Group S.r.l.
