摘要： A method for manufacturing polysilicon, according to the present invention, is capable of manufacturing polysilicon with high purity more efficiently in such a manner that a high-temperature and high-speed air stream is formed at the center of a reaction tube, and a high-temperature region may be formed by a vortex formed by the high-temperature and high-speed air stream, so that a raw gas supplied from the side wall of the reaction tube flows by the guiding of the vortex, thereby increasing a stay time and a reaction time of the raw gas within the reaction tube. Furthermore, since the inner wall of the reaction tube is provided with a heat release means, the rapid cooling of a silicon crystal deposited on the inner wall of the reaction tube can induce a columnar crystal in which the silicon crystal is solidified in a direction perpendicular to a crystal face, and it is easy to desorb the silicon crystal produced by rapid heat release via the inner wall of the reaction tube.
