IPC: C01B33/037
Filed: 1994-11-30
Abstract: PURPOSE:To efficiently remove impurities and to obtain high purity silicon by subjecting silicon to electron beam melting in a crucible put in a melting furnace while keeping the interior of the furnace under a specified pressure. CONSTITUTION:When silicon is melted by heating with electron beams in a crucible put in a melting furnace, electron beam melting is carried out while keeping the interior of the furnace under 1X10<-4>-5X10<-3>Torr pressure. The crucible is preferably a water-cooled crucible and it is preferable that silicon having purity higher than the silicon to be melted is previously melted and the molten high purity silicon is stuck and solidified on the water-cooled crucible in the form of a film. In this method for purifying silicon, clean electron beams are used as a heating source, the atmosphere is high vacuum and the water- cooled crucible is used so as to form a filmlike layer of the same metal as the molten metal on the inside of the crucible. Such advantages of electron beam melting as to prevent the contamination of the molten metal by impurities from the crucible are maximumly utilized.
