Abstract:
Silicon was purified by solvent refining with Si-Sn binary alloy system. Two descend mold velocities, 10mm/h and 100mm/h were tested in directional solidification of the alloy melt. The morphology, structure and the ingredient of the ingots have been investigated by SEM, XRD, EPMA, GDMS and ICP-MS. The contents of Fe, N, C , Ca, Mn, Cu, P and B are significantly lower than that in raw silicon. Furthermore, the acid leaching experiments were introduced to remove tin from silicon. The temperature of acid leaching and the type of acids were the predominant conditions in tin separation from silicon by acid leaching.
