| Abstract Scope |
In this study, pure and La3+/Bi3+ co-doped BaTiO3 powders were synthesized via ball milling followed by thermal treatment. High-purity BaCO3, TiO2, La2O3, and Bi2O3 precursors were used, and stoichiometric calculations were based on the Ba1-3xLa2xTi1-3xBi4xO3 formula, with concentrations of x = 0.000, 0.005, 0.010, and 0.050. Structural characterization was performed using X-ray diffraction and Rietveld refinement, while morphological analysis was conducted by scanning electron microscopy. The XRD and refinement results revealed a tetragonal-to-cubic phase transition at x = 0.010, and the formation of a BaBiO3 secondary phase at x = 0.050, indicating the solubility limit of the dopants. Thermodynamic simulations were carried out to evaluate the phase evolution of the precursor mixtures as a function of temperature. |
