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 900Β°C. The experiments show that Cr doping increases diffusion of Ni in the oxide lattice, but decreases diffusion of Ni along grain boundaries provi
