Abstract

Nanopowders of lanthanide aluminates and ferrites were obtained by aqueous combustion synthesis. Scanning electron microscopy and specific surface area measurement made clear that the morphology and size of powder particles depended on the glycine: nitrate ratio in the initial mixture. The obtained powders consisted of aggregates of particles with the sizes of several nanometers. XRD analysis of the calcined powders did not reveal the presence of phases of individual oxides of rare earth elements (REE), aluminum, or iron, which indicated the completeness of solid state reactions.
