摘要
近几年,光伏产业以30%的速度持续强劲增长。作为原料的半导体工业副产品供应的不足并且在未来10～15年内也不能显著增加的情况下,建立独立的太阳能级高纯硅原料供应体系是不可避免的。从理论上分析了利用真空蒸馏的方法除磷提纯冶金级硅的可行性,并进行了真空条件下脱磷的实验研究。
There was a dramatic increament about 30% per year in photovoltaic industry in recent years. And the raw material of photovoltaic industry is impossible to increase markedly within next 10 - 15 years. Therefore, it is inevitable to establish an independent feedstock system of solar grade silicon （SOG-Si） material. In this paper, a theoretical analysis about the feasibility of phosphorus removal in metallurgical grade silicon with vacuum distillation, then an experiment was conducted.
