Bi(Me)O 3 -PbTiO 3 high T C piezoelectric multilayers

Denis J Cumming; Tutu Sebastian; Iasmi Sterianou; Jürgen Rödel; Ian M. Reaney

Abstract Multilayer structures based on the composition 0·52(0·35Bi(Mg1/2Ti1/2)O3–0·3BiFeO3–0·35BiScO3)–0·48PbTiO3 (BMFS-PT) have been fabricated with large piezoelectric activity and high TC. Reaction with Pt internal electrodes during cofiring leads to a decrease in TC and softening of the ferroelectric response, consistent with donor doping. However, this effect is minimised by extending binder burnout times up to 4 h and in samples with thicker active layers (∼100 μm). Multilayer actuators based on BMTFS-PT should therefore increase the operating temperature to <100°C above PZT structures with equivalent piezoelectric activity.
