Synthesis And Characterization Of Ultra‐fine Zinc Substituted Lithium Ferrites

Ultrafine substituted lithium ferrite having the compositional formula Li0.5‐0.5xZnxFe2.5‐0.5xO4 where 0⩽x⩽1.0 in steps of 0.2 were prepared by the citrate Precursor method. A nitrate citrate gel was prepared from metal nitrates and citric acid, which exhibits self‐propagating combustion behaviour. Spinel structure of the synthesized ferrite was confirmed by XRD analysis. The variation in lattice parameter and density with zinc concentration is studied.
