Abstract

This paper reports a detailed study of the electrostrictive effect and related properties of unpoled ferroelectric ceramics (1-x)/spl middot/PbZrO/sub 3/-x/spl middot/K/sub 0.5/Bi/sub 0.5/TiO/sub 3/, where x=0-1, using a sensitive capacitance dilatometer at room temperature. The material was found to exhibit a large electrostrictive coefficient Q/sub 11/ of /spl sime/0.3 m/sup 4//C/sup 2/ which is more than three times as large as that of single crystal BaTiO/sub 3/. Comparison with PZT ceramics indicates that new material is a potentially useful one for transducer application.

PbZrO/sub 3/-K/sub 0.5/Bi/sub 0.5/TiO/sub 3/陶瓷的电致伸缩性能

本文用灵敏电容膨胀计在室温下详细研究了x=0-1的非极性铁电陶瓷(1-x)/spl middot/PbZrO/sub 3/-x/spl middot/K/sub 0.5/Bi/sub 0.5/TiO/sub 3/的电致伸缩效应及相关性能。结果表明，该材料具有较大的电伸缩系数Q/sub - 11/ // spl sime/0.3 m/sup //C/sup 2/，是单晶BaTiO/sub - 3/的3倍以上。与PZT陶瓷的对比表明，该材料在换能器领域具有潜在的应用价值。
