Abstract:

In this work we propose a new method for synthesis of ultrafine powders of tungsten, titanium and vanadium carbides combining two methods – liquid-phase precipitation on carbon substrate and low-temperature microwave heat treatment in argon stream. An entire spectrum of intermediates obtained by thermolysis, reduction and carbonization of precursors, as well as the final products has been presented. As a result of sample assessment, the phase composition, structure, morphology and particle size, as well as the size of specific surface areas have been determined.
