摘要	In order to improve the corrosion resistance of NiFe(2)O(4) ceramics as inert anode, additive V(2)O(5) was added to raw materials NiO and Fe(2)O(3). The inert anodes of nickel-ferrite ceramics were prepared by powder metallurgic method and the static corrosion rate in Na(3)AlF(6)-Al(2)O(3) was determined by mass loss measurement. The effect Of V(2)O(5) on sintering property and corrosion resistance was studied. The results show that V(2)O(5) can promote the grain to develop completely and improve sintering property. EDS results show the reaction product Ni(2)FeVO(6) distributes along the grain boundary. The corrosion tests show that V(2)O(5) is beneficial to improving corrosion resistance remarkably. The reasons that V(2)O(5) can improve the corrosion resistance must be V(2)O(5) promoting the gains to develop completely and Ni(2)FeVO(6) distributes along the grain boundary. The stable structure can control the chemical dissolution of ceramics anode and the reinforced grain boundary can control the grain-boundary corrosion rate.
