Abstract

Single-phase Bi₅ Ti₃ FeO₁₅ and Bi ₆ Ti₃ Fe₂ O₁₈ ceramics have been synthesized by solid state reaction. The ferroelectric transition of the compounds was studied by differential scanning calorimetry, high-temperature x-ray diffraction, and temperature-dependent dielectric measurements. Two solid-state structural transitions were observed in both compounds, one is the orthorhombictetragonal transition (ferroelectric transition) at 1021 K for Bi₅ Ti₃ FeO₁₅ and 973 K for Bi₆ Ti₃ Fe₂ O₁₈, and the other is accompanied by an abrupt lattice expansion of the tetragonal phase at about 1110 K for Bi ₅ Ti₃ FeO₁₅ and about 1090 K for Bi₆ Ti₃ Fe₂ O₁₈.
