<p>Disclosed is a method for producing silicon by reducing a chloride of silicon, which is characterized in that at least a metal is formed into liquid particles and the metal liquid particles are brought into contact with a gaseous chloride of silicon, thereby producing silicon through reduction of the chloride of silicon. Also disclosed is an apparatus for producing silicon, which is characterized by comprising at least a reaction chamber for reacting metal particles and a gaseous chloride of silicon, a means for heating the reaction chamber, a means for supplying the metal particles into the reaction chamber, a means for supplying the chloride of silicon into the reaction chamber, a means for discharging a fluid from the reaction chamber, and a container for collecting the produced silicon. Consequently, a low-cost silicon polycrystal for solar cells can be produced by such a method and apparatus.</p> |
