| 摘 要： | 对铝电解阴极附近络离子的稳定性及离子分布进行了研究。认为络离子在电极双电层区域内越靠近电极其稳定性越低;各种离子(团)在电极附近均呈指数分布,从而说明了铝电解阴极直接放电的离子是Al_(3+)单体而不是AlF_6~(3-)等络离子。

| Abstract: | The stability of ionic complex and ionic distribution nearby cathode in aluminium electrolysis are investigated. It is shown that in the double-layer charge zone the stability of ionic complex decreases with the distance to electrode, and all the ions or ionic clusters in the vicinity of electrode present their distributions exponentially. The fact reveals that in Al electrolysis the ions directly discharged from cathode are not of such ionic complex as but of single A13 + . |
