摘要
Magnesium aluminate spinel was prepared by auto combustion process using nitrate precursors as oxidizers and glycine as fuel. Different nitrate: glycine ratios were used to study the effect of amount of fuel on the spinel formation. Resultant products were calcined between 600 degrees and 800 degrees C and then characterized for phase analysis. Phase pure Mag-Al spinel was formed at 700 degrees C, for all the compositions. 700 degrees C calcined powders of all the three nitrate: glycine ratios were studied for sintering between 1500 degrees and 1600 degrees C and also the effect of Cr2O3 on sintering behaviour of all compositions were studied.
