摘要: 在NaCl-KCl熔盐体系中, 以AlCl₃作为氯化剂, 通过液相反应将钛的氧化物氯化为TiCl₃。对比TiO、Ti₂O₃、TiO₂的氯化效果, 并综合AlCl₃与TiO、Ti₂O₃、TiO₂反应热力学分析, 较好的结果是Ti₂O₃氯化为TiCl₃。采用不同的电化学测试手段研究了Al (Ⅲ) 与Ti (Ⅲ) 在Mo电极上的合金化过程, 采用共沉积法制备TiAl₂、TiAl₃合金。同时借助于XRD和SEM手段对合金进行了分析, 说明通过熔盐电解可以直接制备Ti-Al合金。

Abstract: This article investigated the feasibility of chlorination of titanium oxides to TiCl₃ in liquid phase using AlCl₃ as chlorinating agent in the molten NaCl-KCl system.Compared with the chlorination results of TiO,Ti₂O₃ and TiO₂ and based on the thermodynamic analysis of reactions of AlCl₃ with TiO,Ti₂O₃ and TiO₂,Ti₂O₃ was selected for chlorination to TiCl₃.Different electrochemical testing means were used to investigate the alloying process of Al（Ⅲ） and Ti（Ⅲ） on the molybdenum electrode and the feasibility of preparation of TiAl₂ and TiAl₃ alloys by codeposition.Alloys were analyzed using XRD and SEM.Thus,it is feasible to prepare Ti-Al alloys by molten salt electrolysis directly.
