Tape casting is a ceramic processing method used to fabricate low-cost SOFC components such as electrolytes and electrodes. Electric field assisted flash-sintering has been attracted recently as a fascinating approach to obtain highly crystalline and dense or porous ceramic materials within few seconds. In the present work, we have applied the flash sintering mechanism for nickel oxide-gadolinium doped ceria (NiO-GDC) porous anode fabricated by Tape Casting, at different temperatures under various DC electric fields. It can be concluded that the electric field influences on the temperature at which the flash sintering occurs and the microstructure with high degree of porosity or densification required to select suitable current density. Furthermore, the temperature for the onset of flash sintering varies from one materials to another and also depends on the contact area between the particles which changes with particle size, porosity and inhomogenity.
