Nanoscale silicon is interesting in various areas, including electronics, photovoltaics, solar and Li-ion energetics. This work describes processes of electric arc sputtering of SiO2 in a graphite electrode in a helium medium, leading to formation of silicon nanowhiskers. A fan- shaped turbulent jet of vapors of the sprayed electrode flowing from the interelectrode space, resulting in formation of areas with different component compositions and temperatures, is considered. Interaction of SiO and Si vapors leads to the formation of the silicon nanowhisker structure.
