Abstract

Several properties associated with the field-induced phase change between the antiferroelectric and ferroelectric states in tetragonal (Pb0.97 La0.02) (Sn,Ti,Zr)O3 antiferroelectric ceramic family were investigated for high-strain displacement transducer applications. The longitudinal field-induced strain accompanying the phase change is in the range of 0.2%-0.9%. The single-shot switching time between the two states is on the order of 1-2 μs. Under continuous ac field driving, the hysteretic heating effect introduces a temperature rise, changing the original room-temperature switching behavior. The ceramics degrade under ac field excitation, the average life cycles is in the range of 106 -107 cycles which can be greatly improved by carefully polishing the sample surfaces.
