文摘

A fine PNN-PZT piezoelectric ceramic was prepared by doping rare-earth method. The MPB structure with the rectangular shape diffraction peak is optimum. The MPB structure related to the change of relaxation behavior in ceramics. The d33 reach to maximum, when the relaxation behavior obviously. The rare-earth Ce improve the electric properties and Cuire temperature of the ceramics.
