ABSTRACT
The features of the purification of technical silicon in helium with molybdenum and graphite cathodes are considered. The formation of silicides and carbides in the melt is substantiated. The effect of melt polarity on the removal of impurities and gases is shown. The evaporation of technical silicon and the interelectrode transfer of elements are quantitatively determined. The efficiency of evaporation and removal of impurities in an electric field is estimated.
