Synthesis and Characterization of Nickel Ferrite: Role of Sintering Temperature on Structural Parameters

Abstract

We synthesized Nanocrystalline nickel ferrite powder using co-precipitation method and studied the effect of sintering at 100, 400, 600, 800 C on the prepared samples. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used to characterize the samples. XRD patterns show crystalline nature of the sample and the spinel structure of NiFe2O4. Particle size and morphology of the nanocrystalline powders were determined by TEM. The average particle sizes were identified to be 10 nm. Results indicate that the chemical synthesis by co-precipitation method leads to obtain nano crystalline nickel ferrite with controllable particle size.
