电解制鋁时,熔融鋁于阴极沉积,阳极处产生氧气,氧与阳极碳素化合生成氧化碳。在很高的工作溫度范圍內,由于氧化作用促使阳极质量恶化,一般每制取1磅鋁消耗的阳极碳素約为0.5～0.6磅,因而制鋁成本中的相当部分是来源于阳极稍耗。专利提出了改良的制鋁用阳极,提供了被 Electrolysis aluminum, the molten aluminum deposition in the cathode, the anode oxygen, oxygen and anode carbon oxides generated carbon. In the high temperature range, due to the deterioration of the anode caused by oxidation deteriorates, the general consumption of each pound of aluminum consumption of anode carbon is about 0.5 to 0.6 pounds, so a considerable part of the cost of aluminum is derived from the anode slightly . The patent proposes a modified aluminum anode that is provided
