摘　　要：采用传统粉末冶金技术制备了铝电解用5Cu/(NiFe2O4-10NiO)金属陶瓷惰性阳极,对其在钠钾冰晶石混合冰晶石中进行电解腐蚀。研究结果表明,从微观来看,阳极存在腐蚀现象。电解过程的槽电压波动剧烈。Fe、Ni和Cu组元的平衡浓度分别为150×10-6、42×10-6及40×10-6,腐蚀速率比常规电解条件下的低。The 5Cu/（NiFe2O4-10NiO） cermet inert anode was developed by classical powder metallurgical technique.The corrosion behaviors of NiFe2O4-based inert anodes in Na3AlF6-K3AlF6 melts were investigated.The results show that the anode had corrosion phenomenon in micro-morphology.Cell voltage fluctuated remarkably during electrolysis.The equilibrium concentration of Fe,Ni,and Cu were 150×10-6,42×10-6 and 40×10-6,respectively,and the corrosion rate was lower than that in tradition electrolysis conditions.
