摘要
在铝电解槽中存在着几类导体,它们的导电机理各不相同。电子是由阴极导入,经过电解质,最终由阳极导出,同时分别发生阳极反应和阴极反应,产生阳极产物CO_2(气体)和阴极产品AI(液体)。新开发的情性电极材料多数可能是电子导体。因为导电机理与铝电解节能有直接关系,所以值得研究。
In the aluminium electrolysis cell, there are various electrical conductors: carbon anode, molten cryo-
lite electroyte, liquid aluminium pad, carbon bottom etc. In modern cell there are inert anode which is built
with metals and metallic oxides, as well as inert cathode made of TiB_2 - C layer and carbon blocks. The electri-
cal conductivity of all these materials relate to the energy consumption in aluminium production.
