Most of the metal impurities in industrial-grade silicon cannot be effectively removed through oxidative refining, slagging, etc., but silicon has physical properties that can be used for effective impurity removal, that is, segregation and impurity removal. The solubility of most impurities in solid silicon is very low, but the solubility in liquid silicon is relatively … Read More
