Abstract

Iron-doped titanate (PbTi₁₋ₓFeₓO₃) was successfully synthesized using the sol-gel autocombustion method, with varying iron concentrations (x = 0.00, 0.02, 0.04, 0.06, 0.08, and 0.1). Elemental composition was determined by EDS, morphology was analyzed using SEM, and ferroelectric properties were evaluated through the P-E loop and PUND methods. EDS confirmed the successful incorporation of Fe into the structure. SEM images showed a reduction in the particle size of PbTiO₃, from 100 nm to 20 nm, suggesting that the presence of Fe ions contributed to the decrease in particle size. Ferroelectric analysis indicated a reduction in polarization, enhanced coercivity, and minimal leakage current at an iron concentration of x = 0.02, making it suitable for energy storage applications.
