Formation of Nanoscale Mg(x)Fe(1−x)O  (x = 0.1,0.2,0.4) Structure by Solution Combustion: Effect of Fuel to Oxidizer Ratio

Mg ( x ) Fe (1− x ) O (magnesiowustite) nanopowder samples synthesized by solution‐combustion method and fuel to oxidizer ratio (Ψ = 1, 1.25) are used as a control parameter to investigate how particle size and morphology vary with Ψ. The method is inexpensive and efficient for synthesis of oxide nanoparticles. The average crystallite size of Mg ( x ) Fe (1− x ) O nanoparticles was estimated from the full‐width‐half maximum of the X‐ray diffraction peaks of powders using Debye‐Scherrer’s formula; the average crystallite size varies from 16 nm to 51 nm. From X‐ray diffraction analysis, it was observed that Mg ( x ) Fe (1− x ) O nanoparticles have cubic structure. The particle size measured by particle size analyzer ranges from 37.7 nm to 73 nm which is in the order of XRD results. Thermal analysis was done by thermal gravimetric‐differential thermal analyzer. The particle size and morphology of the synthesized powder were examined by transmission electron microscope and scanning electron microscope. The crystal size and particle size were compared with some of the most recently published research works by XRD and TEM. FTIR conforms formation of the Mg ( x ) Fe (1− x ) O.
