In this study, copper niobate was synthesized using the solid-state reaction route, aiming to achieve phasepure, highly crystalline samples suitable for detailed structural and electrical investigations. Microscopic studies using SEM and TEM revealed distinct morphological features associated with grain growth, surface texture, and microstructural stability. Complementary spectroscopic techniques, including Raman and FTIR, were used to elucidate the local bonding environment and vibrational modes related to NbO₆ and CuO₆ octahedra. These spectroscopic signatures further validated successful synthesis and structural stability. Thermal behavior and phase transitions were assessed using TGA/DTA, confirming the thermal robustness of the prepared materials. Overall, the research provides a systematic understanding of the synthesis, phase formation, structural characteristics, dielectric response, and electrical/magnetic behavior of copper niobate. The findings contribute valuable insights toward optimizing copper niobate materials for advanced applications in sensors, microwave devices, photocatalysts, and next-generation energy storage technologies such as high-rate lithium-ion batteries.
