Description Stoichiometric and non stoichiometric magnesium ferrite (MgFe2+delta O-4,1, delta=0.0, 0.1) were synthesized by the sol gel combustion method resulting in nanocrystalline powders with size ranging from 10 to 100 nm. These powders were calcined at various temperatures (300-800 degrees C). One part of the calcined powder was quenched in liquid nitrogen and the other part furnace cooled, alpha-Fe2O3 was observed in all calcined samples by XRD and this was also reflected in the magnetization data. Electrical response of MgFe2.104 5. spinet phase to 75 ppm ethanol was found to be greater than that for a stoichiometric magnesium ferrite. (C) 2014 Elsevier B.V. All rights reserved.
