Sol-gel auto combustion synthesis is one of the best chemical methods for the synthesis of ferrite nano-particles. The ratio of fuel to nitrate is an important parameter in obtaining nano-particles of high quality. In the present paper we communicate our experimental results based on the influence of fuel to metal nitrate ratio on the structural properties of nickel ferrite. Nickel ferrite (NiFe 2 O 4 ) nanoparticles were prepared by a well-known sol-gel auto combustion method taking citric acid as a fuel. We have prepared nano-particles of nickel ferrite using different ratios of fuel to metal nitrate 1:1, 1:2, 1:3, and 1:4. These samples are named as NF1, NF2, NF3 and NF4 respectively. All the samples are thermally characterized by TG-DTA. The TG-DTA analysis confirmed the ferritization temperature, which varies slightly as the ratio of fuel to metal nitrate varies. All the samples were sintered at an average temperature of 560 0C for 4 hours and used for further study. XRD was used to study the structure and phase purity of prepared nanoparticles. It has been concluded from XRD analysis that all the samples NF1, NF2, NF3 and NF4 show single phase nature with cubic structure. The crystallite size was obtained by Scherrer’s formula. It is found that the fuel to nitrate ratio influences the structural properties of nickel ferrite.
