Abstract

The secondary phase compositions in Sb-doped (Ba, Sr)TiO₃ ceramics containing SiO₂ and excess TiO₂ sintering additives have been examined by XRD, BEI and EPMA techniques. It is shown that alongside the primary (Ba_0.797Sr_0.2Sb_0.003)TiO₃ phase, (Ba_1.95Sr_0.05)₂(Ti_1.2Si_1.8)O₈ and Sb-doped (Ba_0.99Sr_0.01)₆Ti₁₇O₄₀ phases form at the intergranular regions. Substitution of up to 0.04 mol% MnO₂ enhances the PTCR effect, giving a ratio ρ_max/ρ_min ∼ 7 × 10⁵ for the optimum 0.04% MnO₂ composition. At this level Mn cannot be detected in the microstructure by EPMA, however in insulating samples containing 0.08 mol% of MnO₂, it was detected in the (Ba_0.99Sr_0.01)₆Ti₁₇O₄₀intergranular phase.
