摘要
采用连续变化电导池常数法(CVCC法)系统研究了PrF3-NdF3-LiF-Pr6O11-Nd2O3体系熔盐的电导率。研究发现,该体系熔盐的电导率随温度的升高而增大;随LiF含量的增加而降低。在0~0.6%的REO浓度范围内,熔盐电导率随REO浓度的增加而增加;在0.7%~1.4%的REO浓度范围内,熔盐电导率随REO浓度的增加变化不明显;在1.5%~2%的REO浓度范围内,熔盐电导率随REO浓度的增加而降低。研究结果为优化稀土电解质组分,实现稀土电解生产的节能降耗提供理论支撑。
The conductivity of molten salt in PrF3-NdF3-LiF-Pr6O11-Nd2O3 system was systematically studied by CVCC method.It is found that the conductivity of molten salt increases with the increase of temperature and decreases with the increase of LiF content.In the range of 0~0.6%REO concentration,the molten salt conductivity increases with the increase of REO concentration;in the range of 0.7%~1.4%REO concentration,the molten salt conductivity does not change significantly with the increase of REO concentration;in the range of 1.5%~2%REO concentration,the molten salt conductivity decreases with the increase of REO concentration.The results provide theoretical support for optimizing the composition of rare earth electrolyte and realizing energy-saving and consumption-reducing production of rare earth electrolysis.
