BaTiO₃-based perovskite materials were synthesized and comprehensively characterized by energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), and UV–Vis absorption techniques. EDS analysis confirmed the formation of stoichiometric BaTiO₃ containing 64.2 wt.% BaO and 35.8 wt.% TiO₂, which closely agrees with the theoretical composition. FTIR spectra revealed characteristic absorption bands associated with Ti–O vibrations in TiO₆ octahedra and confirmed the formation of a well-ordered perovskite lattice. UV–Vis measurements demonstrated strong ultraviolet absorption with an absorption edge around 390–400 nm. The optical band gap determined by the Tauc method was approximately 3.1–3.3 eV, indicating wide-band-gap semiconducting behavior. The obtained results demonstrate that the synthesized BaTiO₃ possesses high phase purity, structural stability, and favorable optical properties, making it a promising candidate for dielectric, piezoelectric, photocatalytic, and optoelectronic applications.
