A study has been made of the structural and thermal phase behavior of the mixed system α· Fe2O3·xLi2O with a view toward investigating the changes occurring in the properties of different compositions due to substitution of diamagnetic Li+ for Fe3+ at B sites in the inverse spinel lattice. This also indicates whether the addition of Li2O, over and above that (x = 0.2) required for the formation of the spinel LiFe5O8, enters the substitutional or interstitial sites. Characterization by X-ray powder diffraction, initial magnetic susceptibility, magnetic hysteresis, Mössbauer spectroscopy, and differential thermal analysis clearly indicates that Li+ does not enter the spinel lattice, but forms a biphasic system LiFe5O8 and LiFeO2, which are not miscible.
