摘要: NiFe2O4 ceramic based inert anodes were fabricated by a two-step cold-pressing sintering process. The bubble behavior of was investigated in two-compartment see-through quartz cell. Anodic overvoltage and potential decay curves on the measured using steady state current interruption technique. results show that electrolytic gas evolution for anodes, including nucleation, growth, coalescence, growth again, migration escaping, lasts 79s escaping size is about Φ4mm×2mm. While 102s carbon with larger releasing bubbles. When densities are 0.6, 0.8, 1.0 1.2A/cm2, anodic 0.189 V, 0.270 0.309 V 0.359 respectively. After adding small amount MnO2, V2O5, TiO2, minor reduction can be obtained.
