Investigation of Polyol Process for the Synthesis of Highly Pure BiFeO Ovoid-Like Shape Nanostructured Powders.

Exclusive and unprecedented interest was accorded in this paper to the synthesis of BiFeO nanopowders by the polyol process. The synthesis protocol was explored and adjusted to control the purity and the grain size of the final product. The optimum parameters were carefully established and an average crystallite size of about 40 nm was obtained.
