本文介绍了利用Sc2O3为原料，盐酸溶解后，制备成ScCl3熔盐，再用镁作还原剂，铝作捕收剂制备Al-Sc中间合金的新工艺。降低了Al-Sc中间合金的生产成本，工艺稳定，流程简单，ScCl3的转化率近100%。
The new preparation method of Sc-bearing master alloy has been studied in this paper.Scandium oxide raw material was dissolved in hydrochloric acid,then KCl,NaCl and special stable agent solution were added.ScCl3 molten salt was reduced by Mg at the reduction temperature of 1000～1200K.The new method can reduce the cost of Sc-bearing master alloy greatly.
