Synthesis and charecterization of Magnesium Aluminate spinel by solution combustion method using variation of fuel to oxidiser ratio and mixed fuels

Abstract :

<p>&nbsp;This paper is a study of Nano sized MgAl2O4 (Magnesium Alumminate) spinel powders which were synthesized by muffle furnace assisted Solution Com &ndash;bustion Synthesisusing various mixtures of urea, glycine as fuel. It was seen that Mg(NO3)2.6H2O and Al(NO3)3.9H2O show different behavior with respect to urea and glycine . Also the variation of fuel to oxidizer (F/O) ratio was studied . The study was carried out for leaner to richer fuel ratios.In the case of MgAl2O4 combustion synthesis results were achieved when fuel mixture (urea and glycine) were used. The useof fuel mixtures allowed the formation of pure, nano&ndash;crystalline MgAl2O4 directly from the combustion reaction.The effect of fuel mixture ratios was investigated by variation of the ratios in which the fuel was taken . The later product was characterized by XRay&ndash;diffraction analysis .The nanoscaled images where taken by SEM (Scanning Electron Microscope ) of the powder being produced.</p>
