The piezoelectric ceramics Pb0.94Sr0.06(Zr0.53Ti0.47)O3+(Ni2O3+Cr2O3)0.1wt% + x wt%MnO2 + y wt%CeO2 (abbreviated as PCrNi-4) were prepared by a traditional ceramics process in this paper. The influences of MnO2 and CeO2-doping and sintered temperature on matrix material properties were studied by orthogonal tests. The effects of different inducing factors on the microstructure and dielectric loss were analyzed by means of XRD, SEM and electric measurement. The results indicate that the optimum process conditions are w(MnO2)= 0.1%, w(CeO2)= 0.3% and the sintering temperature 1280°C. The property parameters of samples are: d33=304.8pC/N, Kp=0.6113, εT33=1520, tanδ=0.00289, d33×g33=61.12×10-12CVm/N.
