摘要: Heavily doped barium titanate (BaTiO3) powders, one with a donor-rich and the other an acceptor-rich composition, were prepared. After sintering, specimen exhibited fine-grained microstructure but significant grain growth occurred in specimen. A stable dielectric behavior was observed only over temperature range studied. However, both specimens, undoped core region several hundred nanometers size detected. The core-shell structure appeared to be maintained BaTiO3 under conventional sintering conditions.
