摘要：

Diffusion of Cr in CoO single crystals was studied by using the X-ray microprobe technique. The diffusion coefficient of Cr thus determined exhibits the following temperature dependence in the range 1273-1673 K: [GRAPHICS] The diffusion data obtained are about one order of magnitude higher than those determined for a polycrystalline CoO. The difference is considered in terms of the effect of a segregation-induced diffusive resistance on diffusion data determined for a polycrystalline specimen.
