Well-crystallized, spherical, nanosizes powders were formed by this method. The powders were found to have a cubic structure, which was retained even after heating at 900°C. Sintering at 1400°C, led to the formation of a tetragonal structure with a secondary phase of Ba6Ti17O40. Abrupt grain growth was observed at 1400°C. The electrical response of the sample sintered at 1400°C has three electrically different regions. Each region of the sample is represented by different RC element. Element 1 (R 1 C 1) is the most resistive and its capacitance ishigh (0.5nFcm−1) indicating a thin region, probably the grain boundary. Element 2 (R 2 C 2) shows a smaller resistance value compared to element 1. The capacitance value of element 2 is temperature-dependent and displays a Curie-Weiss behaviour, indicative of a ferroelectric material above T c. The lower capacitance of C 2 (15pFcm−1) indicates that it is a much thicker region than element 1 and can be assigned as a ferroelectric bulk region. Element 3 is probably an electrode effect.
