Abstract

Abstract: The results of experimental studies indicating the possibility of obtaining molybdenum carbide crystalline phases in a dc arc discharge plasma initiated inside a hollow graphite cathode in the air gaseous atmosphere under normal atmospheric conditions are presented. According to the X-ray diffraction data, two molybdenum carbide phases are identified in the powder synthesis product: Mo1.2C0.8 and Mo2C, as well as graphite and metallic molybdenum. According to the transmission electron microscopy data, molybdenum carbide particles are in the carbon matrix and are characterized by dimensions mostly not exceeding 5–10 nm.
