摘要
在实验室铝电解槽上研究了炭阳极消耗。研究结果得出,预焙阳极的炭阳极消耗随阳极电流密度的增加而趋向于理论消耗110％左右。石墨阳极消耗随电流密度增加而略有提高,其范围在135～150％之间。石墨阳极相对于理论的过多消耗主要是由于阳极气体逸出和电解质的搅动引起的。预焙阳极的电化学过程选择性氧化是造成阳极过多消耗的主要原因。
The carbon anode consumption was measured in laboratory aluminium electrolysis cells. The measured results indicated that the carbon consumption of a prebaked anode decreased slightly with increasing anode current density towards a value of about 110% of the theoretical consumption. For a graphite anode a slight increase was observed, and the consumptions were higher in the ravage 135～150%, and the gas evolution and electrolyte stirring may be the main reason for the excess anode consumption. For prebaked anode, however, the selective oxidation may rather be the main cause of the excess anode consumption.
