In this study, CaTiO₃-based perovskite materials were synthesized and characterized to investigate their structural and multifunctional properties. The synthesis was carried out via a modified sol-gel method using calcium and titanium precursors, followed by heat treatment to obtain highly crystalline perovskite phases. X-ray diffraction (XRD) analysis confirmed the formation of a single-phase orthorhombic structure with well-defined crystallinity. Fourier-transform infrared (FTIR) spectroscopy and UV–visible spectroscopy (UV–Vis) revealed characteristic Ti–O and Ca–O vibrations and an optical band gap of 3.2 eV, indicating strong semiconductor behavior. Elemental analysis confirmed the stoichiometric composition of the CaTiO₃ phase. The dielectric and piezoelectric studies showed high permittivity and stable polarization behavior, suggesting potential applications in sensors and capacitor devices. The catalytic activity of the synthesized perovskites was also evaluated, showing promising results for environmental and energy-related applications. Overall, the obtained data demonstrate that CaTiO₃-based perovskites possess excellent structural stability and multifunctional characteristics suitable for advanced technological applications.
