The paper presents the results of the experimental studies demonstrating the possibility of obtaining the crystalline phases of molybdenum carbide in a DC arc discharge plasma initiated inside a hollow graphite cathode under ambient air conditions. According to X-ray diffraction data in the powder synthesis product two phases of molybdenum carbide are identified: Mo1.2C0.8 and Mo2C, as well as graphite and metallic molybdenum. According to transmission electron microscopy data, molybdenum carbide particles are located in the carbon matrix, particles are characterized by sizes mostly not exceeding 5-10 nm.
