摘要: 在等摩尔比的NaCl-KCl熔盐中,采用海绵钛与TiCl4进行等量反应,制备得到含低价钛离子的熔盐。通过计算得到钛离子的平均价态,添加计算量的TiCl4和过量的海绵钛,得到Ti3+离子与Ti0的熔盐,并研究单质Ti与Ti3+的离子反应,结果表明:该反应在0到210 min内为二级反应,对金属钛的熔盐电解制备钛粉的研究有着积极意义。Abstract: The molten salts containing titanium ions with lower valence state were prepared by the reaction of titanium sponge and TiCl4 in NaCl-KCl molten salts(molar ratio of NaCl∶KCl=1∶1). The average valence state of titanium ions was calculated, and then the molten salts with Ti3+ and Ti~0 were obtained by reaction between TiCl4 of calculated amount and excess titanium sponge. The ion reaction of Ti and Ti3+ was investigated. It is indicated that the reaction at 0~210 min is of second order. The results in this paper have directive significance on titanium powder preparation by molten salts electrolysis.
