摘要
本文介绍了利用 Sc2 O3为原料 ,盐酸溶解后 ,制备成 Sc Cl3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 ,Sc Cl3的转化率近 10
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.ScCl 3 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.
