Synthesis and Characterization of Electrical Properties of Bismuth Titanate

Bismuth titanate solid solutions, Bi12+xTiO10+delta (0 <= x <= 0.6), were synthesized by conventional solid state method at sintering temperature of 700 degrees C for 48 h. Structural studies were performed by powder X-ray diffraction (XRD) analysis and revealed that single-phase materials were obtained with a general formula of Bi12+xTiO10+delta (0 <= x <= 0.6). The electrical properties of all the single-phase samples were studied using the impedance spectroscopy technique. Further characterization of the materials was carried out using differential thermal analysis (DTA) and indicated that no phase transition was observed. The TGA analysis was observed and found that all the materials were thermally stable.
