摘要

亚微米晶粒尺寸的PZT-5A陶瓷已经生产出与传统粗粒材料相当的性能。新的掺杂策略补偿了随着晶粒尺寸减小而导致的介电和压电性能下降。这使得材料的压电性变软，补偿了极化效率的降低。亚微米粒度材料已被证明优于粗粒陶瓷在细尺度切割操作。

Processing and structure-property relationships for fine grained PZT ceramics

Submicron grain sized PZT-5A ceramics have been produced with properties comparable to conventional coarse grained material. The degradation in dielectric and piezoelectric properties with decreasing grain size was compensated with a new dopant strategy. This made the materials piezoelectrically softer compensating for reductions in poling efficiency. The submicron grain sized material has been shown to be superior to coarse grained ceramic during fine scale dicing operations.
