Modified Combustion Synthesis of Nanocrystalline Nickel Ferrite

Nano crystalline nickel ferrite was synthesized using modified microwaved assisted combustion method using mixtureof fuels (diethylene triamine pentaacetic acid (DTPA) and Ethylene diamine tetra acetic acid (EDTA)). Effect of fuel tooxidizer ratio on crystallite size has been investigated in 3 levels (0.75, 1 and 1.25). The products were calcined at800°C for 2 hr. The structure, morphology and magnetic properties of the synthesized powder were characterized bypowder XRD, EDX Mapping and N2 sorption (BET) analyses. XRD data confirm the formation of the single phasespinel nickel ferrite compound in the range of 13 to 17 nm. The elemental composition of the synthesized compoundwas evaluated by EDX mapping and results showed a perfect distribution of the elements (i.e. Ni, Fe and O).
