| 摘 要： | 针对稀土金属Ｎｄ的氟化物体系熔盐电解中石墨阳极所存在的一系列不足，研制了一种新型的电极材料，称其为非碳阳极；并对其在电解过程中的腐蚀机理进行了较详细的探讨，提出了还原反应、氧化反应、电解质渗透、电极组分溶解、析氧膨胀等几种可能的腐蚀原因．与此同时，作者还将在轻金属铝电解中应用较成功的２种惰性阳极进行了稀土熔盐电解实验，实验结果否定了其在稀土电解中应用的可能性．

| Abstract: | Because of the disadvantages in the electrolysis of rare earth metals, a new kind of electrode material called non-carbon anode is studied, and the corrosion mechanism is reseached.The main corrosion reasons may be reduced reaction, oxidize reaction, electrolety permeate,solution of the electrode expending and so on. Two kinds of inert anodes which are fit for Al electrolysis are used in rare earth metals electrolysis. The result shows that they are riot suitable for rare earth metals. |
