Recent developments in the preparation, sintering process,
mechanical properties, and thermal shock resistance of cermet inert anodes for aluminum
electrolysis are reviewed in this paper. To obtain the desired technologies of low-temperature
activated sintering of cermet inert anodes, the effects of material composition, sintering
atmosphere, sintering temperature, and sintering aids on the densifi cation and microstructure of
NiFe2O4-10NiO- based ceramics and cermets were studied. To obtain the toughening and
strengthening technology of the cermet, the effects of material composition including ceramic and
metallic phases are discussed. The cermet inert anodes with high density and mechanical
properties were prepared through adjustment of material composition and sintering technology and
selection of feasible sintering aids.
