N2 - In this paper, Pb(Zr,Ti)O3-Pb(Zn1/3Nb 2/3)O3-Pb(Sn1/3Nb2/3)O 3-Pb(Mn1/3Sb2/3)O3 (named briefly PZT-PZN-PSN-PMS) quinary system piezoelectric ceramics with various Zr/Ti ratio were prepared by traditional method. The properties of this quinary system piezoelectric ceramics were studied and the effect of Sr2+, Ba 2+ doping on dielectric constant εr3T and Curie temperature Tc were investigated. What's more, the dielectric loss tan δ and dielectric constant εr3T under the strong alternating electric (AC) field were discussed. The partial substitution of Pb2+ with Sr2+ and Ba2+ improves εr3T and decreases slightly Tc. The tan δ and εr3T under strong AC fields sharply increase because of the movement and vibration of domain walls resulting from AC field. The good general results are as follows: Qm = 1671, εr3T = 1294, d33 = 285 × 10-12CN-1, tan δ = 0.004 (1 V/mm field), K p = 0.522, Tc = 295 °C and the coercive electric field Ec = 19 kV cm-1. When AC field increases to 200 and 400 V/mm, tan δ is equal to 0.013 and 0.041, respectively. The above results were obtained for the certain composition doping 2 mol% Sr2+ and 2 mol% Ba2+.
