摘要：
The electrical properties of donor doped BaTiO3 samples with a donor concentration >0.3 mol% were studied. Samples were sintered at a low partial pressure of oxygen in order to facilitate the,anomalous grain growth and donor incorporation. In order to optimise the PTCR anomaly the samples were annealed in an oxidising atmosphere. The samples were characterised using impedance spectroscopy and SEM. Results show that by the use of a specific sintering profile PTCR ceramics containing a higher amount of donor dopant can be prepared. (C) 1999 Elsevier Science Limited. All rights reserved.
