Investigation on mechanochemical combustion behavior of Mg-V2O5-Co3O4-C reactive system to synthesize VC-Co nanocomposite powder

摘要

VC-Co nanocomposite powders were obtained by mechanochemical combustion synthesis from a mixture of V2O5, Co3O4, C and Mg powders. The synthesized powders were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (LEM). VC Co nanocomposite was directly produced after 10 min milling through a mechanically induced self-sustaining reaction without further heat treatment. TEM analysis showed that a nanostructured powder with a mean particle size of 100 nm was procured in the sample milled for 10 min. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
