摘要：

In this study, in order to develop low-temperature-sintering ceramics for multilayer piezoelectric actuator, Pb(Mg1/2W1/2)O-3-Pb(Ni1/3Nb2/3)O-3-Pb(Zr,Ti)O-3 (abbreviated as PMW-PNN-PZT) ceramics were fabricated using Li2CO3 and CaCO3 as sintering aids and their dielectric and piezoelectric properties were investigated with the amount of Pb(Ni1/3Nb2/3)O-3 (abbreviated as PNN) substitution. PMW-PNN-PZT composition ceramics could be sintered up to 870A degrees C by adding sintering aids. At the sintering temperature of 900A degrees C, electromechanical coupling factor (k (p)), piezoelectric constant (d (33)) and Curie temperature (Tc) in the composition ceramics with 9 ;mol% PNN substitution showed the optimal value of 0.64 517 ;pC/N and 317A degrees C, respectively for multilayer actuator application.
