Abstract

Nanosized yttrium orthoferrite was obtained by the heat treatment of an X-ray amorphous precursor prepared by the glycine-nitrate combustion process in orthorhombic and hexagonal phases with average crystallite sizes of 27-33 nm and 6-11 nm, respectively. The processes controlling YFeO3 formation under the specified conditions were shown to be the decomposition of yttrium carbonate and yttrium oxycarbonate. The transition from the metastable hexagonal phase to the stable orthorhombic phase in YFeO3 was shown to occur when the hexagonal YFeO3 crystallites reach sizes of 15 +/- 5 nm. The YFeO3 nanoparticle size distribution was analyzed to suggest a phase transition scheme.
