研究了自制钛可溶阳极Ti CxOy(x≈0.50,y≈0.50)在简单氯化物(Na Cl-KCl)熔盐体系、低价钛离子浓度为3.5%的(Na Cl-KCl-Ti Clx)熔盐体系中的电化学溶解行为,同时考察了相应体系下的阴极行为。结果表明,在上述两种熔盐体系中,阳极Ti CxOy(x≈0.50,y≈0.50)均能发生电化学溶解。在简单氯化物熔盐体系中不利于得到阴极产物;在含低价钛离子的熔盐体系中有利于阴极产物的稳定得到,阳极的电流效率能够稳定在50%以上(以三价钛放电计算),阳极的溶解率从简单氯化物(Na Cl-KCl)熔盐体系中的80%左右下降到50%。
The effects of Ti CxOy (x ≈0.50, y≈0.50) on the simple chloride (Na Cl-KCl) molten salt system, low content of NaCl-KCl-TiClx with 3.5% Electrochemical dissolution behavior in molten salt system, and the cathodic behavior under the corresponding system was also investigated. The results show that in the two molten salt systems, the anode Ti CxOy (x ≈ 0.50, y ≈ 0.50) can be dissolved electrochemically. In the simple chloride molten salt system is not conducive to the cathode product; in the molten salt system containing low-cost titanium ions is conducive to the stability of the cathode product, the anode current efficiency can be stabilized at 50% (calculated by trivalent titanium discharge ), The anode dissolution rate decreased from about 80% in simple chloride (Na Cl-KCl) molten salt system to 50%.
