The article is devoted to the study of the chemical-physical properties of tungsten borides of the W-B system obtained from tungsten-containing multicomponent mineral raw materials of the Far East region by local high-energy exposure using an ionized plasma flow with a specific power of 10–100 kW/cm2. The authors study the nature of processes and properties of the materials obtained during high-temperature plasma synthesis. We determined the chemical and phase composition of the synthesis products, including compounds of the W-B system, and studied the morphology of the formation and growth of boride crystals. For identification purposes, we used X-ray phase and spectral microanalysis methods, as well as scanning electron microscopy. By means of laboratory sample tests, we confirmed the experimental synthesized material contains W-B system tungsten borides and established the presence of phase compounds: WB, WB2, and W2B.
