| Abstract: The solid state interaction of the Zn1-xCoxO nominal system is investigated by means of diffusion couples and analysis of co-precipitated samples. The formation of a homogeneous Co:ZnO solid solution is found to be determined by the crystal structure from which Co-II ions diffuse into the wurtzite lattice. No diffusion is observed whenever the CoO rock-salt Structure is formed from the Coll precursor. Oil the contrary, the diffusion from the Co3O4 spinel phase is feasible but has a limited temperature range defined by the reduction at a high temperature of Co-III-Co-II, since this Process again leads to the formation of the rock-salt structure. However, when using a highly reactive and homogeneous co-precipitated starting powder, neither the spinel phase nor the rock-salt Structure is formed, and a Co-II:ZnO solid solution is obtained. which remains stable Lip to high temperatures.
