摘要：

The segregation behavior of Sn, In, Cu, Ge, and Ag impurities (0.1-0.0001 wt %) was studied during directional solidification of Ga in a boat and purpose-designed rotating crystallizer. The effective segregation coefficients were determined. The use of the rotating crystallizer makes it possible to notably enhance the purification efficiency.
