The Bi2O3 doped 0.35PNN-0.60PZT-0.05V2O5 ceramics were prepared by the conventional solid phase reaction method.The sintering characteristics, crystal structure, microstructure morphology,and dielectric properties were investigated by the Xray diffraction,scanning electron microscope (SEM).The results showed that Bi2O3 additives could lower the sintering temperature,affect the phase structure,changed the micromorphology and optimize the dielectric properties of 0.35PNN0.60PZT0.05V2O5 ceramics.The 0.35PNN-(0.60-w%)PZT+005V2O5+w%Bi2O3 ceramics doped with mass fraction of 1.0% Bi2O3 sintered at 900 ℃ had the optimal dielectric properties with the piezoelectric constant of d33=580 pC/N，electromechanical coupling coefficient of kp=0.65，dielectric constant of εr=6 100，dielectric loss of tan δ=0.006 1，and quality factor of Qm=65.
