摘要：Synthesizing carbon-encapsulated ferronickel nanoparticles was developed by a detonation method. The composite precursors were ignited in the nitrogen in closed explosion vessel. These composite nanoparticles were characterized with transmission electron microscope, energy-dispersive X-ray spectrometer, X-ray diffraction, X-ray fluorescence, Raman spectroscopy and magnetic measurement. Results indicated that carbon-encapsulated ferronickel nanoparticles with diameters ranging from 10 to 50 nm were produced and the composite nanoparticles were with a core-shell structure. The composite nanoparticles were synthesized with the yield about 10-15% one time. (C) 2010 Elsevier B.V. All rights reserved.
