Abstract

The effect of dc electric field upon the spatial variation of microstructure during the sintering of BaTiO₃ in a N₂ atmosphere was investigated. When BaTiO₃ specimens were heat-treated in a N₂ atmosphere at 1350 °C under an electric field, grain growth was enhanced at the positive-biased region for a 0.5 mol% Nb-doped specimen, while it was promoted at the negative-biased region for a 3.0 mol% Nb-doped specimen. The grain growth behavior at both the positive and negative-biased region was similar for a 1.0 mol% Nb-doped specimen. The results have been explained mainly in terms of the boundary potential, which varies with the donor concentration, and the oxygen partial pressure of the surrounding atmosphere.
