Glass-Self-propagating low temperature (SPLT) route for synthesizing nanomaterials has been gaining importance in the field of synthetic technology by being a cost effective, faster and cleaner approach when compared to the other conventional and wet chemical methods for the synthesis of metal oxide nanoparticles. In the present work, synthesis of strontium iron oxide (SrFe2O3) nanoparticles viz., were carried out by SPLT route through the thermal decomposition of strontium iron metal oxalate precursors employing polyvinyl alcohol (PVA) as a fuel. The characterization was developed for size and structure by employing Fourier transform infrared (FTIR) spectral studies. The morphology of the samples ranged from nano spherical to agglomerated irregular-shaped particles for strontium ferrite samples based on the results of field emission scanning electron microscopy (FESEM) images. Possible gas sensing applications of these ferrite sample nanoparticles are studied.
