[Abstract]:Metallurgical method is an effective means to reduce the impurity content in metallurgical grade silicon gradually. It is an effective means to prepare solar grade polysilicon. It shows huge cost compression space and has great potential for development. In order to further reduce metallurgical cost, scholars at home and abroad are aiming at the long process, low purification efficiency and so on. A lot of research work has been carried out on the key problem, and a variety of effective methods are used to strengthen the removal of impurities in the process of metallurgical silicon purification, and the purification efficiency of polysilicon is enhanced. The latest research progress on impurities removal in the process of solidification refining and slag refining is mainly summarized, and the latest research progress on the removal of impurities in the process of solidification refining and slag making is reviewed. The research focus and development prospect of the next stage of metallurgy are prospected.
