Preparation of TiV Alloy by Electrolysis-Deoxidization in Molten Salt

摘要:

在CaCl2熔盐中电解混合氧化物合成TiV合金。电解电压为3.0~3.2 V，电解温度为900 ℃，钛、钒混合氧化物作为阴极，石墨棒作为阳极。初步研究了电解原理。结果显示，反应过程是混合氧化物逐步还原生成组分可控的TiV合金。还原经历了从优先生成钛到逐步形成TiV合金的合金化历程。中间产物包括CaTiO3、钒和钛的低价氧化物。

Abstract:

TiV alloys were prepared by electro-deoxidization method. Using molten CaCl2 as electrolyte, mixed oxides of sintered V2O5 and TiO2 as cathode, and graphite rod as anode, the samples were electrolyzed at 900 ℃ under 3.0-3.2 V. The electrolysis principle was studied. Results show the reaction process is gradual reduction of mixed oxides to produce content-controllable TiV alloys. The process is prior production of Ti subsequent to gradual production of TiV alloy. The intermediate products include CaTiO3, V4O9 and TiO et al.
