Abstract

Materials Science Materials Science, Ceramics Science & Technology Technology
We show that multilayer green tapes constituted from sandwiched layers of NiOzirconia anode and cubic zirconia electrolyte can be sintered below 1000 degrees C in a few seconds under the influence of a DC electric field. The sintering yields a dense electrolyte layer with minor closed porosity, and an anode layer with open porosity, and, most importantly, a multilayer that is largely devoid of defects and delamination.
