In the present study, it was aimed to investigate the synthesis of iron based magnetic aluminium oxide nanocomposites (IMANCs) by solution combustion (SC) method using various fuel types at various amounts. IMANCs were synthesized using aluminium nitrate and iron nitrate as oxidizers. Urea, glycine and sucrose were chosen as fuel types at various amounts, respectively, to examine their effects on size and morphology of nanocomposites synthesized. The chemical compositions, morphologies and thermal behaviors of IMANCs synthesized were compared with data obtained from characterization studies using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS), Thermogravimetric and Differential Thermal Analysis (TG/DTA), Fourier Transform Infrared Analysis (FT-IR), Surface Area and Porosity Analyzer. The characterization studies revealed that IMANCs were synthesized successfully by SC method with nanoscale properties. It was found that IMANCs synthesized using stoichiometric amount of glycine had porous and smaller particle size with higher surface area compared to other samples synthesized by urea and sucrose, respectively. There is no documentation found on glycine based synthesis of IMANCs by SC method in the literature so far. Additionally, this original paper is the first report on the synthesis of IMANCs by applying calcination and reduction processes following SC reaction using various fuel types at various amounts. It was resulted that the samples synthesized by SC method had smaller particle sizes compared to the samples which were synthesized by applying calcination and reduction processes following SC reaction using stoichiometric amount of urea, glycine and sucrose as fuel types, respectively.
