在多层压电器件的研制过程中,为实现压电陶瓷和Ag/Pd内电极的共烧结,本文对中温1100~1140°C范围烧成的PZN-PZ-PT系压电陶瓷的电性能进行了研究,结果表明,保温时间对该组成的压电介电性能有重要的影响,随保温时间的延长,d33从420×10-12C/N增加到560×10-12C/N,εT33从2180增加到2900.

In order to realize the co-sintering with Ag/Pd electrodes in multilayer devices, PZN-PZT piezoelectric ceramics were prepared by a conventional technique in the sintering temperature range from 1100C to 1140C and their piezoelectric and dielectric properties were carefully studied. The results show that soaking time is the most important factor concerning with piezoelectric and dielectric properties, d33 increases from 420×10-12C/N to 560×10-12C/N and εT33 increases from 2100 to 2900 with the increase of soaking time.
