Synthesis And Charecterization of Magnesium Aluminate Spinel By Solution Combustion Method Using Variation of Fuel to Oxidiser Ratio and Mixed Fuels

This paper is a study of Nano sized MgAl 2 O 4 (Magnesium Alumminate) spinel powders which were synthesized by  muffle furnace assisted  Solution Com -bustion Synthesisusing various mixtures of urea, glycine as fuel. It was seen that Mg(NO 3 ) 2 .6H 2 O and Al(NO 3 ) 3 .9H 2 O 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 MgAl 2 O 4 combustion synthesis results were achieved when fuel mixture  (urea and glycine) were used. The useof fuel mixtures allowed the formation of pure, nano-crystalline MgAl 2 O 4 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-diffraction  analysis .The nanoscaled images where taken by SEM (Scanning Electron  Microscope ) of the powder being produced.
