The Metal - Oxide Composite [Fe0.2Co0.8]0.8[Fe2.38Co0.62O4]: Hrtem and EDX Characterization
Published online by Cambridge University Press: 21 February 2011
Abstract
The new metal-ferrite composite [Fe0.2Co0.8]0.8[Fe2.38Co0.62O4] is obtained by precipitation of ferrous and cobalt chloride in KOH. Further heating under vacuum above 400°C shows a cationic exchange between metal and spinel leading to a new composite made up of cobalt metal and cobalt doped magnetite.
HTERM and EDX observations have been carried out on both composites, i.e., before and after vacuum annealing, We show that cationic exchange occurs mainly in crystals made up of spinel, CoO and amorphous nanoparticles.
