熔盐电解制备Al-Cu-Y合金电解质体系黏度的研究

Investigation on viscosity of electrolysis system for preparing Al-Cu-Y alloy via molten salt electrolysis

摘要

摘要: 采用旋转法测定了熔盐电解制备Al-Cu-Y合金的电解质体系Na₃AlF₆-AlF₃-LiF-MgF₂-Al₂O₃-CuO-Y₂O₃在温度900~1 000 ℃范围内的黏度，通过分析数据研究温度及Al₂O₃、Y₂O₃、CuO添加量对熔盐黏度的影响，确定了温度、熔盐组分和黏度之间的关系.结果表明：在温度900~1 000 ℃范围内，体系随温度升高，黏度减小；随Al₂O₃、Y₂O₃、CuO的含量增大，黏度增大；在900~1 000 ℃范围体系黏度（η）随温度（T）以及氧化物的含量W_Al₂O₃、W_Y₂O₃、W_CuO符合回归方程η=0.075-6.49×10^-5T+3.7×10^-4W_Al₂O₃+5.73×10^-4W_Y₂O₃+6.78×10^-4W_CuO.

Abstract: The viscosity of electrolyte of Na₃AlF₆-AlF₃-LiF-MgF₂-Al₂O₃-CuO-Y₂O₃ eutectic system, which is used to prepare Al-Cu-Y alloy via molten salt electrolysis, was determined by rotation method in the temperature range of 900~1 000℃.The relationship between temperature, molten salt composition and viscosity was determined by analyzing the viscosity data of molten salt at different temperatures and in different contents of Al₂O₃, Y₂O₃ and CuO. The results showed that the viscosity decreased with the increase of temperature in the range of 900~1 000℃, but it increased with the rise in the content of Al₂O₃, Y₂O₃ and CuO. The variation of viscosity(η) with temperature(T) and oxide content (W_Al₂O₃、W_Y₂O₃、W_CuO) was coincided with the regression equation: η=0.075-6.49×10^-5T+3.7×10^-4W_Al₂O₃+5.73×10^-4W_Y₂O₃+6.78×10^-4W_CuO.
