We developed piezoelectric ceramics suitable for high-power piezoelectric transformer applications. Sb, Li, and Mn were substituted in the 0.8Pb(Zr 0.5Ti0.5)O3-0.16Pb(Zn1/3Nb 2/3)O3-0.04Pb(Ni2/3Nb2/3)O 3 ceramics. All these substituents changed the structure of a tetragonal composition to cubical phase. The Sb and Li substitutions resulted in increases in kp and d33, whereas Mn substitution increased Qm. The composition 0.8Pb(ZrxTi 1-x)-0.2Pb[(1 - c){(1 - b)(Zn0.8Ni0.2) 1/3(Nb1-aSba)2/3-b(Li 1/4(Nb1-aSba)3/4)}-c(Mn 1/3(Nb1-aSba)2/3)]O3 (a = 0.1, b = 0.3, c = 0.3, and x = 0.5) showed kp = 0.56, Qm = 1951 (planar mode), d33 = 239 pC/N, ε3 T0 = 739 and a maximum vibration velocity = 0.6 m/ s in the 31 mode. By adjusting Zr/ Ti ratio, the structure of the ceramics reverted to the morphotropic phase boundary and showed kp = 0.57, Qm = 1502 (planar mode), d33 = 330pC/N, ε 3T0 = 1653 and a maximum 31 mode vibration velocity = 0.58 m/s when Zr/Ti = 0.48/0.52.
