Abstract

In order to satisfy EIA X8R specification, a new type of BaTiO ₃-based ceramic with hierarchical structure in a formula scheme "a ferroelectric ABO ₃ + another ferroelectric ABO ₃", was designed. There were (Ba, Bi)TiO ₃ and Ba(Ti, Zr)O ₃ phases with different Curie temperatures coexisting in the grains from inside to outside, prepared by wet chemical method under 100 °C. The hierarchical structure of the ceramic grains was proved by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The dielectric constant of (Ba, Bi)TiO ₃-Ba(Ti, Zr)O ₃ ceramic was ∼6000, the ΔC/C _{20 °C} was -12.0%, 14.1%, and -8.3% at -55 °C, 130 °C, and 160 °C, respectively, and the dielectric loss is less than 0.1, which is obviously superior to (Ba, Bi)TiO ₃ and Ba(Ti, Zr)O ₃. The results of this work showed that the formula scheme "a ferroelectric ABO ₃ + another ferroelectric ABO ₃" for solid solutions is a promising approach to prepare high performance temperature-stable capacitor materials.
