In this paper you can see the results of experimental studies that are devoted to the production of powder. To obtain these materials, an electric arc method without vacuum was used, based on the effect of spontaneous shielding of the reaction zone by gaseous products of combustion of a direct current arc discharge in the gap between graphite electrodes. A feature of the approach used is its implementation without the use of vacuum equipment. The process of electric arc synthesis is implemented in a cylindrical cavity of a graphite cathode, in which a powder mixture of carbon and molybdenum is present. As a result of experiments, multiphase powder products were obtained, which were collected from various parts of the discharge loop electrode system. Three types of products were obtained: collected from the walls of the cylindrical cavity of a graphite cathode, collected from its bottom, and also collected in the form of a cathode deposit. Differences in the phase composition of the products obtained were revealed, and the morphology of micro-sized particles in the synthesis product was determined.
