The effect of fuel to nitrates ratio on the properties of FeCr2O4 nanopowders

Abstract The solution combustion of spinel type FeCr 2 O 4 nanopowders via different ratios of fuel to stating metal nitrates was investigated. The synthesized FeCr 2 O 4 nanopowders were deemed to be single phase spinel type material based on powder X-ray diffraction, FTIR and EDS studies. The properties of synthesized FeCr 2 O 4 nanopowders such as morphology, porosity, elemental composition, crystallite size, strain and lattice deformations, magnetic moment, and coercivity were influenced by the amount of the fuel used in the combustion process. FeCr 2 O 4 nanopowders with different morphologies, porosities, structural, and magnetic properties could be prepared in a single procedure on a hotplate magnetic stirrer without the need for high temperature furnaces.
