Аннотация

This paper studies the possibility of obtaining ultrafine cubic titanium carbide in the direct current arc discharge initiated between graphite electrodes in ambient air. According to X-ray diffraction data, there are 3 crystalline phases in the synthesized powder: Graphite, initial titanium and cubic tungsten carbide. Based on transmission electron microscopy data, particles with sizes of 100-300 nm containing titanium and carbon are identified in the synthesis product. These objects are characterized by a structure corresponding to the cubic phase of titanium carbide. The applied vacuumless electrotechnical method is known for its ease of implementation, high productivity, and high energy efficiency in comparison with electrical analogues.
