Abstract
Method and apparatus for refining metallurgical grade silicon to carry out deboronization rapidly in production of silicon for solar cells, by blowing a plasma gas of steam and inert gas on a surface of molten silicon, and wherein a reducing gas is further applied to the molten metal surface, and including the further step of controlling mix ratios of steam and reducing gas, the angle of blowing of the gas, and the deboronization parameters.
