Abstract
Single- and polycrystals of (Mg, Me)O (Me = Fe, Co, Ni) have been oxidized or reduced under appropriate conditions of oxygen partial pressure, at temperatures ranging from 973 to 1673 K The reaction always occurred internally and yielded a two-phase layer. The growth kinetics of this layer were measured and can be interpreted in terms of cation diffusion. The variability of the microstructures developed is emphasized and the effect of temperature, oxygen partial pressure and initial concentration in Me are discussed.
