Study on Phosphorus Removal from Metallurgical Grade Silicon by Vacuum Distillation

摘要：

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.
