In this paper, (Pb 0.9 Sr 0.1 )(Zn 1/3 Nb 2/3 ) (0.06+ x ) (Ni 1/3 Nb 2/3 ) 0.16 (Zr 0.52 Ti 0.48 ) (0.78- x ) O 3 (PSZN-PSNN-PSZT, x = 0, 0.02, 0.04, 0.06, 0.08) piezoelectric ceramics were prepared by traditional solid-state reaction method. The samples were studied on microstructure, phase structure, electrical properties and dielectric relaxation. All as-prepared PSZN-PSNN-PSZT ceramics present single phase of perovskite structure. Experimental results show that the variation trend of the R phase percentage content is consistent with the trend of d 33 . Also, increasing PSZN content will inhibit the growth of sample grains. The temperature-dependent of dielectric performance testing results present that all the samples possess obvious relaxation behavior. The best overall performance of the samples are obtained at x = 0.06, where its d 33 = 920pC/N, k p = 0.71, P r = 24.54 μ C cm −2 , γ = 1.98, ε r = 6856, tan δ = 3.3%, T c = 133 ℃. The PSZN-PSNN-PSZT ceramics are potential candidate materials due to its simple preparation process, the high dielectric and piezoelectric properties.
