摘要：

High-Curie-point semiconducting barium-lead titanate PTCR ceramics of composition Ba0.897Pb0.10La0.003TiO3 were prepared. The electrical properties of grain and grain boundary of the sample were studied by a combination of complex-plane impedance analysis and impedance spectra methods. The PTC originated only in the grain boundary material. © 1990.
