Abstract

CuO-doped 0.8Pb(Mg1/3Nb2/3)O3-0.2PbTiO3 (0.8PMN-0.2PT) ceramics were prepared by the reaction-sintering method. X-ray diffraction (XRD) measurement, scanning electron microscopy (SEM) observation and density measurement confirmed that the CuO-doped 0.8PMN-0.2PT ceramics prepared by the reaction-sintering method with the addition of up to 5 mol% CuO and sintered over a wide sintering temperature range exhibit pure rhombohedral perovskite structure, rather homogeneous micromorphology and high relative density. As compared to the undoped 0.8PMN-0.2PT ceramics prepared by the same method, CuO proves to be an effective sintering aid, which can greatly decrease the sintering temperature of the 0.8PMN-0.2PT ceramics prepared by the reaction-sintering method, where high relative density can be obtained and the electrical properties are not deteriorated or improved of the synthesized 0.8PMN-0.2PT ceramics. The CuO doping content and sintering temperature exert great influences on the crystal structure, density and electrical properties of the 0.8PMN-0.2PT ceramics prepared by the reaction-sintering method.
