Removal of Boron from Silicon by Solvent Refining Using Ferrosilicon Alloys
Abstract
The distribution of boron between purified solid silicon and iron-silicon melt was evaluated to investigate the possibility of boron removal from silicon by solvent refining with iron-silicon alloys. The distribution coefficient, defined as the ratio of the mole fraction of boron in solid to that of liquid, was found to be strongly dependent on boron concentration. Solvent refining at lower temperatures resulted in smaller distribution …
