摘要：
Ceramic in PZT-PFN system with a formula 0.9Pb(Zr1/2Ti1/2)O-3-0.1Pb(Fe1/3Nb2/3)O-3 was prepared by a conventional solid state mixed oxide technique. The phase formation behavior and microstructure were investigated using x-ray diffraction (XRD) and scanning electronmicroscopy (SEM), respectively. The dielectric properties of the compound were examined and discussed. Phase-pure perovskite of the 0.9PZT-0.1PFN ceramic was obtained at sintering temperature of 1100 degrees C. The average grain size decreased significantly from 1.27 mu m in PZT to 90.2 nm in 0.9PZT-0.1PFN. In addition, the dielectric properties of the ceramic showed two phase transitions between rhombohedral to tetragonal ferroelectric phases, and then tetragonal ferroelectric to cubic paraelectric phases at transition temperature of 150 degrees C and 350 degrees C, respectively.
