Abstract

This paper reports an observation of the electrostrictive effect of a barium doped PZT paraelectric ceramic using a sensitive capacitance dilatometer at room temperature. This sintered material was found to exhibit a large electrostrictive coeffiecient Q₁₂ of − 0.27 m⁴/C² which is five times as large as that of single crystal BaTiO₃. Comparison with a very strong piezoelectric PLZT at the same field strength indicates that Ba: PZT is a potentially useful material for transducer application.
