Synthesis of tungsten carbide–carbon nanomaterials by combustion reaction

Abstract It has been studied the possibility to synthesize the new catalytic systems, based on a carbon carrier precipitated tungsten carbides, under the self-propagating combustion regime. For this purpose the tungsten (VI) oxide deposited on a surface of the fine-grained carbon black was reduced by magnesium under the combustion mode. Uniform structures of WC or W 2 C nanosized phases were observed, depending on the preparation of the initial carbon black–tungsten oxide mixtures.
