We report, synthesis of nano crystalline YFeO3 powders by solution combustion process using alanine (C3H7NO2) as a fuel at stoichiometric ratio. The yttrium-nitrate hexahydrate (Y(NO3)3.6H2O) and ferric nitrate nonahydrate (Fe(NO3)3.9H2O) were used as oxidizers. The prepared powders were characterized by X-ray diffraction (XRD) for phase analysis and scanning electron microscope (SEM) for microstructure. The experimental results confirmed the formation of phase pure crystalline yttrium ferrite by comparing the peaks of XRD pattern of the sample with the peaks of standard XRD pattern of JCPDS card number 39-1489 of YFeO3. Crystallite size of the powder was 46 nm, when calculated using Scherer formula. The SEM shows the formation of porous agglomerated particles of nanopowders.
