Abstract
This paper reports a detailed study of the electrostrictive effect and related properties of unpoled ferroelectric ceramics (1-x)·PbZrO3-x·K0.5Bi0.5 TiO3, where x=0-1, using a sensitive capacitance dilatometer at room temperature. The material was found to exhibit a large electrostrictive coefficient Q11 of ≃0.3 m4 /C2 which is more than three times as large as that of single crystal BaTiO3. Comparison with PZT ceramics indicates that new material is a potentially useful one for transducer application
