Glycine-nitrate combustion synthesis of nonstoichiometric Mg-Fe spinel nanopowders

Nanopowders based on MgFe2 + delta O4 + 1.5 delta (delta = 0.1-8.0) Mg-Fe spinels with an average crystallite size from 45 to 60 nm have been prepared by glycine-nitrate combustion synthesis. As a result of the high combustion temperature (near 1330A degrees C), the phase composition of the synthesized powder corresponds to the equilibrium one.
