Abstract: In order to realize the co-sintering with Ag/Pd electrodes in multilayer devices, PZNPZT piezoelectric ceramics were prepared by a conventional technique in the sintering temperature range from 1100℃ to 1140℃ 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.

Key words: middle temperature sintering, PZN-PZT, piezoelectric property, dielectric property
