在CaCl_2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CaTiO_3、钒和钛的低价氧化物.
TiV alloys were prepared by electro-deoxidization method. Using molten CaCl_2 as electrolyte, mixed oxides of sintered V_2O_5 and TiO_2 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 CaTiO_3, V_4O_9 and TiO et al.
