摘要

A series of lead magnesium niobate-lead titanate (PMN-PT) relaxor ferroelectrics have been produced via attrition milling and the columbite precursor method.These were synthesized in order to study the effect of La-doping and Ta-replacement of Nb on PMN-PT ceramics.La-doping led to a decrease in K_(max) (maximum permittivity),T_(max) (temperature of maximum permittivity),and average grain size.With increasing Lanloping levels the PMN-PT ceramic exhibited relaxor-ferroelectric-like behavior as its dielectric constant spectrum became more diffuse.Ta replacement of Nb in PMN-PT ceramics led to PMTa-PT (lead magnesium tantalate-lead titanate) ceramics whose overall dielectric constant spectra were similar to that of the PMN-PT.B-site precursor processing,columbite precursor processing,and conventional mixed-oxide processing all yielded monophasic perovskite PMTa-PT ceramics after sintering at 1200°C.
