摘要：

CuO-doped 15Pb(Sc1/2Nb1/2)O-3-51Pb(Mg1/3Nb2/3)O-3-34PbTiO(3) (PSN-PMN-PT) ternary piezoelectric ceramics were synthesized by two-step columbite precursor method. The addition of CuO leads to full densification and well developed grain of the ceramics at a low sintering temperature of 950 degrees C. Meanwhile, the moderate CuO content significantly improves the phase transition temperature and piezoelectric properties. The optimal comprehensive properties are obtained in PSN-PMN-PT-0.125 wt%CuO ceramics: Tr-t = 120 degrees C, T-c = 185 degrees C, d(33) = 518 pC/N, d(33)* = 853 pm/V, k(p) = 0.58, P-r = 27.8 mu C/cm(2), and E-c = 6.8 kV/cm. Moreover, excellent pyroelectric current temperature stability is also observed in this composition. These results indicate that low temperature sintered CuO doped PSN-PMN-PT ceramics are promising candidates for application multilayer piezoelectric devices and pyroelectric infrared detectors applications.
