Dielectric properties of Pb(Zn1/3Ta2/3)O3-introduced (Ba,Pb)TiO3 ceramic system

Ceramic powders of the Pb(Zn1/3Ta2/3)O3- introduced BaTiO3–PbTiO3 system were prepared using a B-site precursor method. Perovskite formation tendencies of the system compositions were determined by X-ray diffraction. Weak-field low-frequency dielectric properties of the sintered ceramics were investigated. Dielectric constant spectra were further analyzed in terms of diffuseness. Internal microstructures of the ceramics were also examined.
