摘要： An improved anode assembly for an aluminum electrolysis cell is formed by the process of shaping an anode 10 and a cermet connector 12 from powders, machining said articles, and sintering said articles. The cermet connector mates with the anode via a threaded joint located at its region of high temperature 14 during operation thereof to avoid excessive ohmic losses. Mechanical support can be provided by the threaded joint or through the use of separate mechanical suspension bars 22.
