Search and improvement of methods for obtaining materials with promising properties is currently one of the main tasks of industry. This paper presents the study of operation modes of a threephase lowpower arc reactor on the example of tungsten carbide compound synthesis. The use of a threephase discharge configuration provides an increased yield of final products. Pure carbon and tungsten powders were used as initial samples. According to the results of the experiment, a powder based on tungsten carbide was obtained, WC and W2C phases were identified in the powder composition. In addition, the process of tungsten carbide synthesis was accompanied by registration of arc reactor parameters. Using an infrared camera, measurements of the graphite components surface temperature of the system were carried out with further construction of the thermal field distribution matrix. The gas mixture registration emitted during the synthesis processconfirmed the formation of a gas layer consisting of CO and CO2 compounds, which prevents oxidation of the final product of synthesis. The registration of electrical parameters of the system is also an important aspect in the study of operation modes of the arc reactor. According to the results of the work, it was determined that the estimated amount of energy input is ~ 0.3 kWh, the readings from the electric meter are ~ 0.33 kWh.
