Method for purifying silicon |
| abstract |
A method for purifying silicon, which is characterized in that a silicon containing impurities is melted by a plasma flame in a reduced pressure atmosphere and then an oxidizing gas is sprayed onto the thus-obtained silicon melt, so that the impurities are removed therefrom. The method can remove impurities, particularly boron and phosphorus from silicon more efficiently at lower cost when compared with conventional methods for purifying silicon. |
