Phase development and dielectric characteristics of the Pb(Mg1/3Ta2/3)O3-modified Pb[(Zn1/3Ta2/3),(Mg1/3Nb2/3)]O3 system

The effects of Pb(Mg1/3Ta2/3)O3 substitution to a multiple-octahedral system Pb[(Zn1/3Ta2/3),(Mg1/3Nb2/3)]O3 on perovskite phase development and dielectric characteristics are reported. Selected composition powders of the modified system were prepared using a B-site precursor method. Development of the B-site precursor and perovskite phases were investigated by X-ray diffraction. Low-frequency weak-field dielectric properties of sintered pellets were examined. Phase transition modes reflected in the dielectric constant spectra were further analyzed in terms of diffuseness parameters.
