<p>Process for producing solar grade silicon wherein a reduction reaction preferably the reduction of SiF4 by sodium metal (12) is carried out by jetting a spray (62) of reactants into a reaction chamber (80) at a rate and temperature which causes the reaction to take place far enough away from the entry region to avoid plugging of reactants at the entry region and wherein separation in the melt (82) is carried out continuously from the reaction and the Si (90) can be cast directly from the melt. </p> |
