<p>The invention concerns a method for refining silicon, consisting in filling a cold induction crucible (1) with solid silicon; liquefying the crucible content; carrying out, using the induction crucible, a turbulent mixing of the silicon bath (b) by bringing up the liquid from the bottom of the crucible towards the free surface along the crucible central axis; directing a plasma (f) generated by an induction plasma torch (2) towards the bath surface for a time interval enabling the elimination of impurities for which the plasma reactive gas (gr) is adapted.</p> |
