The results of experimental studies proving the possibility of synthesis of molybdenum borides crystalline phases by atmospheric AC arc discharge are presented. According to X-ray diffractometry, there are four crystalline phases Mo2B, MoB, MoB2 and Mo2B5 in powder products obtained at different atomic ratios of molybdenum and boron. According to scanning electron microscopy data, molybdenum boride particles are characterized by a wide size distribution from 10 μm to 100 μm forming agglomerates with sizes up to ~ 550 μm. Keywords: molybdenum boride, arc discharge, alternating current, vacuum-free method.
