ABSTRACT
Considered common methods for cleaning silicon melts. Substantiated removal of impurities in the electric field. The influence of the composition, temperature, helium purity, transmitted electricity and electric field strength is estimated. The removal of polyatomic and multimolecular ions in an electric field has been established. The relative contribution of the interelectrode transfer and evaporation to the purification of silicon is determined.
