Progress in studies of NiFe_2O_4 spinel based cermet inert anodes

The progress in the studies of inert anode which was made by NiFe2O4 based cermet was reviewed in this paper. The main processing for the inert anode made by NiFe2O4 based cermet was summarised. This materials has the advantages of the low solubility in the fluoride melt containing dissolved alumina, the low electrical conductivity and the resistance to the anode oxygen, but it also has the problems of the poor resistance to the thermal shock and the bad connecting property to external current conductors.
