The gel formed in the synthesis of Mg(Fe_0.8Ga_0.2)₂O₄ powder from corresponding metal nitrates and glycine was studied by thermal and IR spectral analyses. Being a bidentate ligand, glycine was established to initiate the gel combustion reaction resulting in the oxide of the above composition. Based on the data on ΔH₂₉₈° and Cp of the reagents and reaction products, the thermodynamic parameters of this process were calculated.
