Description
Summary:In the present research, NiO-GDC nano-composite and Ni-GDC cermet are studied comparatively. The change in microstructure and conductivity before and after reduction has been reported. NiO-GDC nano-composite samples are prepared by solution combustion synthesis. As-synthesized powders are reduced in H2 atmosphere at 500 °C for 5 hr. These samples are characterized by XRD and FE-SEM to confirm phase purity and microstructure respectively. The conductivity measurement of both NiO-GDC and Ni-GDC samples is measured by two probe and four probe method respectively. Drastic change in conductivity is observed after reduction of NiO-GDC to Ni-GDC.
