The possibility of production of finely dispersed composite materials of Mo-TiC composition by simultaneously reducing titanium tetrachloride and molybdenum pentachloride in a methane-hydrogen plasma was studied. Optimum conditions of reducing titanium tetrachloride in the gas mixture were determined. The influence of methane content in the vapor and gas mixture on the properties of the titanium carbide was investigated. Diffraction was used to determine the phase of the reduction products. A micro-x-ray spectral analysis made by scanning electron microscopy established that the highly dispersed powders of molybdenum-carbide composite obtained are characterized by a high uniformity of TiC and Mo. It was found possible to produce composite ultradispersed powder materials directly in the plasmachemical process and thereby eliminate long mixing of composite components.
