Processing and Properties of PSZN-PZT Quaternary Piezoelectric Ceramics


Article Preview

Piezoelectric Pb(Sn1/3Nb2/3)O3-Pb(Zn1/3Nb2/3)O3-PbTiO3-PbZrO3 (PSZN-PZT) quarternary ceramics with varying Zr/Ti ratio, which locate in the vicinity of the morphotropic phase boundary (MPB), were prepared by the conventional calcination route. The conventional and twice synthesis methods were compared. XRD patterns indicated the more complete perovskite phase was formed by the twice synthesis methods. The sintering behavior was investigated. The microstructure was studied and the piezoelectric and ferroelectric properties and the properties under high electric field were determined. The optimized results were obtained when the ratio of Zr/Ti is 43/45 and the sintering temperature is 1260°C.
