The objective of this research is to study the influence of the substitution of Zn on Fe-site to the dielectric properties of LaFeO3. A series of LaFe1-xZnxO3 perovskite materials (x = 0.03 and 0.05) were successfully synthesized by the sol-gel method and then sintered to form bulk samples. XRD, SEM, and EDAX characterized the structure and element composition. The RLC-Meter used to measure electrical properties as well as resistance, dielectric constant, and tan loss. All compounds were single-phase, with no impurity phase. X-ray diffraction analysis showed that all samples have orthorhombic crystal structure and Pbnm space group. The SEM results of the bulk samples showed that the morphology of the particles was uniformly distributed. The electrical properties of LaFe1-xZnxO3 (x = 0.03 and 0.05) in the frequency range of 0.1 kHz-1000 kHz at room temperature were determined by impedance spectroscopy. Zn-doped LaFeO3 leads to an increase in the semicircular diameter Nyquist plot, impedance value, dielectric loss, and material conductivity. These results prove that zinc doping enhances the electrical properties of the material.
