摘要
介绍了太阳能级多晶硅的主要提纯工艺,并提出了冶金法提纯多晶硅的工艺过程,与现在主流的改良西门子法进行提纯效率、成本、耗能以及多环境的影响等方面进行对比。
Due to the development of solar-grade polysilicon purification of proposed new requirements.The main solar-grade polysilicon purification process was described.A set of metallurgical silicon purification process was proposed.The current mainstream methods for the purification of siemens were improved.The cost,energy consumption and other aspects of the environmental impact were contrasted.
