| Abstract |
| 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 600o and 800oC and then characterized for phase analysis. Phase pure
Mag-Al spinel was formed at 700oC, for all the compositions. 700oC calcined powders of all the three nitrate:glycine
ratios were studied for sintering between 1500o and 1600oC and also the effect of Cr2O3 on sintering behaviour of
all compositions were studied. |
