Electromagnetic semi-continuous directional solidification (ESCDS) was employed to separate and purify Si from Sn-30Si alloy. The experimental results indicate that the enrichment of primary silicon reaches approximately 91% as the solidification rate is 1.5 mm/min high. While Ca and B are removed b...
