| Shrnutí: | Title screen HfTaTiNbZrC5 high-entropy carbide micropowder has been synthesized using the technique of direct-current plasma arc discharge at atmospheric pressure. The synthesis was carried out in air atmosphere under conditions of the formation of a protective carbon monoxide gas layer. TiO2, ZrO2, Nb2O5, HfO2, and Ta2O5 oxide metal powders included in the composition of high-entropy carbide with characteristic grain dimensions of 5–10 µm have been used as raw feedstock. It has been shown that it takes at least 90–100 s for the formation of high-entropy carbide to occur from raw feedstock under the action of arc discharge plasma. The advantage of the proposed method of producing high-entropy carbide micropowder compared to other similar methods is the short time of synthesis of such powder with low energy expenditure (~960 kJ/g) and the possibility of using simple equipment for synthesis.
