| 摘 要： | 采用5Cu--9.5NiO--85.5NiFe2O4金属陶瓷阳极在不同的低温铝电解质体系中进行测试.用扫描电镜和X射线衍射对电解后阳极的微观结构进行研究;用电感耦合等离子体原子发射光谱测定电解后产品铝和电解质中杂质元素含量,计算并比较不同电解质组成条件下的阳极腐蚀速率.结果表明:向Na3AlF6--30AlF3体系添加质量分数约为20%的K3AlF6,该阳极表现出好的耐腐蚀性能.

| Abstract: | 5Cu-9.5NiO-85.5NiFe2O4 cermet anodes were tested in different low-temperature electrolytes for aluminum electrolysis.Post-electrolysis microscopic examination of the anodes was carried out by scanning electron microscopy(SEM)and X-ray diffraction(XRD).The contents of impurities both in the bath and aluminum were measured by inductively coupled plasma atomic emission spectrometry(ICP-AES).The corrosion rates of the anodes in different electrolytes were calculated and compared.The results indicate that when t... |
