Abstract

In order to prepare lead-free BaTi03-based positive temperature coefficient of resistance (abbreviated to PTCR) ceramics, 2.0, 4.0, 6.0, 8.0, 10 mol% of Bi_1/2Na_1/2TiO₃ (abbreviated to BNT) added Ba_0.92Sr_0.08TiO₃ (abbreviated to BST) were fabricated by the conventional solid state reaction. Phase and microstructure characterizations revealed that no obvious BNT phase was found in the final sintered BNT-added BST ceramics, indicating that the BNT phase and BST phase formed a solid-solution during sintering. Without doping other special elements, an obvious PTCR effect was observed in the BNT-added BST samples sintered at 1350 °C in air. To reveal the origin of PTCR effect in the BNT-added BST ceramics, the dielectric properties were also investigated. The BNT-mixed BST (abbreviated to BST-BNT) PTCR ceramics exhibited higher Curie temperatures than that of BST sample.
