本文介绍了稀土金属在铝中的作用和对铝及其合金性能的影响,以及铝—稀土的应用。重点研究了2.7NaF·AIF_3—CaF_2—LiF—MgF_2一RE_2O_3—Al_2O_3系工业电解质的熔盐物化性质,并对铝—稀土电解过程中的一些基本问题作了综合性评述。
This article describes the role of rare earth metals in aluminum and its effects on the properties of aluminum and its alloys, as well as the application of aluminum - rare earths. The physical and chemical properties of molten salt of 2.7NaF · AIF_3-CaF_2-LiF-MgF_2-REF2O-3-Al_2O_3 series industrial electrolytes were studied emphatically, and some basic problems in the electrolysis of aluminum-rare earth were reviewed.
