We have measured the diffusion of aNi radiotracer into polycrystalline NiO. nominally doped with 0.1% Cr (Cr/Ni ratio) in the temperature range 600 to 900°C. The experiments show that Cr doping increases diffusion of Ni in the oxide lattice, but decreases diffusion of Ni along grain boundaries provi
The transport properties of Li-doped NiO and (Li þ Ca)-doped NiO were investigated in the high temperature region up to 1073 K. All the oxide samples were prepared by a sol-gel method followed by a sintering procedure. The wet-chemical processing is efficient to prepare oxide ceramics due to shorten
