2.7NaF·AlF_3—Al_2 O_3(4wt%)—CaF_2(2wt%)—MgF_2(1.5wt%)—LiF(变量)—RE_1 O_3(变量)熔体的密度随 RE_2 O_3 浓度增加而增大,随 LiF 浓度和温度升高而下降。电解生产铝稀土合金时,液志铝和电解质之间的密度差,比生产普通铝时更显著,这对提高电流效率有利。
The density of 2.7NaF · AlF_3-Al_2O_3 (4wt%) - CaF_2 (2wt%) - MgF_2 (1.5wt%) - LiF (variable) -RE_1 O_3 (variable) melt increases with the increase of RE_2O_3 concentration, Concentration and temperature rise and decline. Electrolytic production of aluminum rare earth alloys, liquid aluminum and electrolyte density difference between the more common aluminum than the more significant, which is conducive to improving the current efficiency.
