Abstract

PbSnO3-Pb(Mg1/3Nb2/3)O-3-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. d(33)=similar to 530 pC/N, k(p)=similar to 56.4%, Q(m)=similar to 570, epsilon(r)=similar to 3070, tan delta=similar to 0.3%, P-r=similar to 28.9 mu C/cm(2) and E-c=similar to 8 kV/cm.
