摘要：
An attempt has been made to synthesize nano-crystalline Li0.5Fe2.5O4 by solution combustion technique as well as solid state reaction route. Various characterization methods like XRD, TG-DTA and FTIR are employed to validate the structure and phase purity. The electrical relaxation studies have been represented with modulus and impedance at different temperatures. The dc conductivity and hopping frequency are thermally activated and their activation energies found to be in the range of 0.64-0.59 eV for combustion synthesis where as it is found to be 0.89-0.84 for solid state synthesis.
