据美国道·康宁公司的V·D·Dosaj等人报道,他们把化学方法与物理方法相结合,从电弧炉中的硅制得太阳级硅。该法是用某种活性气体吹入熔融状态的硅来提高冶金级硅的纯度。该种气体有效地降低了杂质硼、磷、重金属的含量。这样就从具提纯性气氛的电弧炉硅 According to V.D. Dosaj et al. From Corning Incorporated in the United States, they combined chemical and physical methods to produce solar-grade silicon from silicon in an electric arc furnace. The law is to use some reactive gas into the molten silicon to improve the purity of metallurgical grade silicon. The gas effectively reduces the content of impurities boron, phosphorus and heavy metals. This is from a purely electric arc furnace silicon
