Аннотация
We describe a method of obtaining ultrafine boron carbide (B13C2) powder using the effect of a dc electric arc on a mixture of initial reactants containing carbon and boron. A peculiarity of the proposed method is that it can be implemented using arc discharge operating in open air without any vacuum equipment and protective inert gas atmosphere. X-ray diffraction data showed that the synthesized product in the general case contained three crystalline phases: boron carbide (B13C2), graphite (C), and boron oxide (B2O3). Electron-microscopic examination showed that the average size of boron carbide particles ranged from ~50 nm to ~2 μm.
