FIELD: nanotechnologies.
SUBSTANCE: invention refers to manufacture of electrolytic silicon in the form of nanofibres or microfibres with the use of raw material - silicon dioxide. Essence of invention: method for obtaining silicon nano- or microfibres consists in the fact that SiO2 electrolysis process is performed in melt LiF (0÷3) - KCl (10÷50) - KF (5÷50) - K2SiF6(5÷45) - SiO2 (2÷5) wt % at temperature of 650-800°C and cathode current density of 0.005-1.5 A/cm2 with further silicon sediment detachment from surface of cathode-substrate and electrolyte.
EFFECT: obtaining nanofibrous or microfibrous high-quality silicon with required fibrous structure at relative simple implementation of the process.
