Abstract

PbSnO3-Pb(Mg1/3Nb2/3)O3- PbTiO3 (PSn-PMN-PT) ternary ceramics were successfully prepared by two-step columbite precursor method. The effects of Sn content on the phase structure and electrical properties of PSn-PMN-PT were investigated. X-ray powder diffraction (XRD) results indicated that all studied PSn-PMN-PT compositions located around the morphotropic phase boundary (MPB), with rhombohedral and tetragonal phases coexisted. With the decrease of Sn content, no change was observed in the XRD patterns of PSn-PMN-PT, while pyrochlore phase presented with excess Sn. The piezoelectric, dielectric and ferroelectric properties of PSn-PMN-PT were found to be improved with deficient Sn and deteriorate with increasing Sn content. In particular, the optimum piezoelectric and ferroelectric properties were achieved for PSn-PMN-PT ceramics with 0.2mol% deficient Sn, i.e. d33=~530 pC/N, kp=~56.4%, Qm=~570, εr=~3070, tanδ=~0.3%, Pr=~28.9 μC/cm2 and EC=~8 kV/cm.
