N2 - The effects of lead content on the structure and electrical properties of Pb((Zn1/3Nb2/3)0.5(Zr0.47Ti 0.53)0.5)O3 ceramics were investigated. Specimens with various lead concentrations were prepared by the conventional oxide-mixing method. When the lead concentration was slightly less than the stoichiometric amount, a large amount of pyrochlore phase was formed along with the perovskite phase. On the other hand, excessive amounts of lead led to the formation of PbO on the surface of the specimen. These second phases were seriously detrimental to electromechanical properties. The highest piezoelectric properties were observed when an excess of 1 mol% lead was added. By optimizing the specimen composition, excellent piezoelectric and dielectric properties (kP = 0.7, d33 = 490 pC/N, and εm = 15000) were obtained.
