| Abstract: | Taking Fe2O3 and NiO as main raw materials with Cu of 5% , NiFe2O4 inert anode was successfully prepared by powder metallurgical method. The results show that the best process to synthesize NiFe2O4 spinel is at 1100 - 1200 ℃ for 6 hours. Cold isostatic pressing and subsequently vacuum sintering method was adopted to synthesize Cu -NiFe2O4 inert anodes. The results indicate that the best process to synthesize Cu - NiFe204 is at 1300℃ for 8h. Then , aluminum electrolytic experiment was made at 960 ℃. According to X -ray diffraction of electrolyzed anode, its chemical corrosion mechanism in cryolite melt is discussed. |
