Abstract
Un método para la producción de silicio cristalino que tiene una concentración de hierro menor que la concentración de hierro de las aguas madres, dicho método se caracteriza porque se introducen las aguas madres de silicio fundido contaminando con hierro a una temperatura superior que el punto de fusión de silicio puro en un molde manteniendo el molde a una temperatura suficiente como para hacer que los cristales de silicio crezcan allí,
