| Abstract: | Several kinds of NiO-NiFe_2O_4 based cermet electrodes were developed.A better technique for preparing cermets has been discovered.The determination and mechanism of electrical conductivity of the cermets were presented,which showed the electric conductivity of cermets prepared by chemical copper-plating was better than by mechanical copper-mixing.Finally the corrosion rate of the cermets was determined,when theywere used as inert anode in Aluminum reduction. |
