Kurzbeschreibung (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 T C. Reaction with Pt internal electrodes during cofiring leads to a decrease in T C 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.
