Preparation of PNN-PZT Ceramics and Piezoelectric Characteristics

The experimental basis formula selected in this experiment is 0.1Pb (Ni1/3Nb2/3)O3-0.9Pb (Zr0.42Ti0.58)O3 (PNN-PZT). The traditional solid phase synthesis are applied piezoelectric ceramic samples. The relationship between the microstructure and electrical properties of the ceramic samples are analyzed by means of XRD, SEM, impedance analyzer etc. The XRD patterns show that all the ceramics exhibited a tetragonal perovskite structure. Through the analysis of the ceramic samples of piezoelectric and dielectric properties, PNN-PZT piezoelectric ceramics will possess best comprehensive properties when sintering temperature at 1190°C.
