Effect of the Liquid‐Phase Characteristic on the Microstructures and Dielectric Properties of Donor‐ (Niobium) and Acceptor‐ (Magnesium) Doped Barium Titanate

Year: 2003

Type: article

Abstract: Changes in the microstructure and dielectric properties with the variation of the donor/acceptor ratio in BaTiO 3 ceramics were investigated. In donor‐rich specimens, a liquid that appeared during sintering did not penetrate into grain boundaries. However, in the acceptor‐rich specimens, the grains were separated by a liquid film during sintering. The much higher mobility of the liquid film than that of the grain boundaries was suggested to cause extensive grain growth in acceptor‐rich BaTiO 3 . The macroscopic homogenization of dopants because of grain growth in acceptor‐rich specimens resulted in changes in the dielectric properties.
