DENSITY STUDY OF PRODUCTS OF NANOSCALE FE-CO SYSTEMS SYNTHESIS

Abstract

Synthesis of Fe-Co nanopowders (NP) is researched. NP are prepared by reduction of metal precursors in water solution with hydrazine-hydride, including the stage of intermediate preparation – mixed metal hydroxides (MMH). Phase and crystalinity structure of intermidiates and NPs are investigated by method of X-ray diffraction. Both intermediates and were studied; the results prove that the degree of transformation of the intermediate into nanometals is controlled by synthesis circumstances.
