Summary:Title screen
Ultra-refractory micropowder of the Hf-Ta-C system was synthesized using a DC atmospheric plasma electric arc discharge. The synthesis was carried out under the conditions of burning a DC arc discharge in an air environment due to the formation of a protective autonomous atmosphere from carbon dioxide and carbon monoxide gases. Hafnium and tantalum oxides and X-ray amorphous carbon were used as precursors. The main advantages of this method are simplicity of implementation, short time of the synthesis process, relatively low specific energy costs (less than 300 kJ / g), as well as the availability of equipment used for experiments. The results of studies have shown the possibility of synthesizing tantalum and hafnium carbides by the developed method. However, the product also contains phases of graphite and metal oxides, which is a disadvantage at this stage and a subject for further research.
