The anode effect is a characteristic phenomenon in molten salts electrolysis, especially in aluminium electrolysis. When it occurs,there appear many small electric sparks on the anode,and the cell voltage increases suddenly.In this paper the anode effect was studied by means of cathode-ray oscillography. The back electromotive force of the aluminium electrolysis cell with various kinds of anode materials(carbon, graphite, platinum and other inert materials)was measured,It was clearly observed that a series of electrochemical decomposition processes took place when the anode effect occurred on carbon anodes. The values of back EMF of these processes were in the range of 1.0-5.5V. These were checked with thermodynamics calculations. A direct short circuit of current from anode to cathode was also observed during the whole process of the anode effect.These phenomena were compared with those observed on microelectrolysis cells, and the mechanism of the anode effect was suggestsd.

阳极效应是融盐电解中的一种特殊现象。尤其是在铝电解中,最为普遍。当其发生时,槽电压突然升高,阳极上出现许多细小的电弧。本文采用阴极射线示波术研究阳极效应时的波形和反电势。用活性阳极(炭、石墨)和惰性阳极(Pt,ZrO_2,SnO_2,Al_2O_3)。阳极效应时清楚地观测到一系列的电化学分解反应。测得的反电势值在 1.0~5.5V 范围内。用热力学计算加以核对。还观测到电弧短路现象。这些现象同微型电解槽上所观测到的作比较,进而讨论阳极效应的机理问题。
