Analysis of the influence of fuel on NiFe2O4 nanocrystalline obtained by solution combustion synthesis

This paper investigates the effect of different fuels used on a structural properties stoichiometric composition of NiFe2O4 obtained from the combustion synthesis. Precursor solutions were prepared from iron nitrate nonahydrate and nickel nitrate hexahydrate, and complexing agents as maleic anhydride, oxalic acid and sucrose. The samples were characterized by X-ray diffraction to evaluate the presents phases, and crystallite size from single-line method, specific surface area (BET) and scanning electron microscopy (SEM) for morphological analysis of powders. The results indicate that NiFe2O4 can be obtained after heat treatment at 800 deg C with particle size of approximately 60nm. (author)
