Objective: Nickel ferrite nanoparticles with dimensions below 30 nm have been synthesized by sol-gel auto-combustion process. The nitrate-citrate gels were prepared from metal nitrates and citric acid solutions under various molar ratios of the metal nitrate to citric acid of 1, 2, 3 4 and 5 by sol-gel process. The results showed that nitrate citrate gels exhibit a self propagating behaviour after ignition in air at room temperature. The ratio of nitrates to citric acid also affects the combustion process. The as-prepared powder was annealed at 5000C for 6 hrs. The phase composition and structural properties of the obtained samples are investigated by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). Analysis of the XRD patterns showed the presence of α-Fe2O3 phase and other refractions corresponding to cubic spinel structure. The lattice constant obtained from XRD data increases with metal nitrate to fuel (citric acid) ratio. PACS No: 75.50.Gg, 74.25.Ld, 43.35.Cg
