Nano-crystalline nickel ferrite (NiFe2O4) was synthesized using combustion process with metal nitrates as Ni and Fe ion sources and polyacrylic acid (PAA) as a chelating agent. The effect of ethylene glycol (EG) addition to polyacrylic acid on the synthesis of nano-crystalline NiFe2O4 powders was investigated through DSC, FTIR, SEM and XRD measurements. Thermal behavior, structural coordination, microstructure and crystalline phase formation of as prepared and also calcined polymeric intermediates were, respectively, obtained from the analysis of DSC, FTIR, SEM and XRD results. The crystallite size was calculated using XRD data and Scherrer's formula. The smallest crystallite size is found to be 14 nm for the phase pure NiFe2O4 powder obtained from the polymeric intermediates, calcined at 450 °C for 12 h, synthesized by PAA based gel combustion route with the total metal ions to EG ratio (M/EG) of 1:0.5.
