| Abstract Scope |
Barium titanate (BaTiO₃, BT) continues to attract considerable research interest due to its remarkable dielectric, piezoelectric, and ferroelectric properties, which are essential for a wide range of advanced electronic applications. In this work, BT was synthesized using the hydrothermal method, and 1 wt. % Nb⁵⁺ was incorporated as a substitutional dopant. The results showed that X-ray diffraction (XRD) confirmed the formation of a high-purity tetragonal perovskite phase, as evidenced by the characteristic splitting of the (002)/(200) reflections at 2θ ≈ 45°. Raman spectroscopy corroborated these results by revealing bands at approximately 303, 517, and 720 cm⁻¹, which are characteristic of the tetragonal phase and correspond to the internal vibrational modes of the TiO₆ octahedra. Finally, scanning electron microscopy (SEM) was employed to evaluate the microstructure, morphology, and grain size distribution, revealing the influence of Nb⁵⁺ incorporation on the microstructural evolution of BT. |
