Notes:
Ni-YSZ cermets were prepared by combustion synthesis of Y(NO3)3, Zr(NO3)4, Ni(NO3)2 andurea followed by hydrogen reduction at 800°C. The microstructure and electrical conductivity of Ni-YSZcermets were investigated as contrasted to those of the cermets with the same Ni contents prepared bymechanically mixing method. The cermets prepared by combustion synthesis method had betterhomogeneity of Ni distributed in YSZ than those prepared by mechanically mixed method; thus, both Niand YSZ phases formed, to a certain extent, a continuous network structure. The electrical conductivity ofthe cermets prepared by combustion synthesis method was always better than that obtained with thesamples prepared by mechanically mixed method
