Abstract
Calcium ferrite nanoparticles were synthesized using sol-gel auto-combustion and co-precipitation methods to investigate the influence of synthesis technique on structural, magnetic, morphological, and electrical properties. X-ray diffraction confirmed orthorhombic crystal structures in both methods, with enhanced crystallinity observed in sol-gel samples. VSM analysis revealed higher saturation magnetization in sol-gel products, while FE-SEM images showed more uniform particle morphology and reduced agglomeration. FTIR spectra confirmed efficient organic decomposition in sol-gel samples. Additionally, sol-gel-derived nanoparticles exhibited superior dielectric constants and AC conductivity. Overall, the sol-gel method offered better control over phase purity, magnetic strength, and electrical behavior, making it more suitable for advanced applications, while the co-precipitation method remained effective for simpler, cost-efficient synthesis.
