Abstract:

The structure and preparation methods of spinel cobalt blue pigments，including solide phase，liquid phase and gaseous phase processes were introduced. The effects of different iron-doping methods on the structure and properties of modified cobalt blue pigments were investigated with XRD，SEM techniques. Bivalent cation-doping influenced the lattice constant of the pigments in agreement with the law of Vegard. Tribalent cation-doping had an obvious influence on the tone of the pigments. Finally the development of cobalt blue pigments in terms of preparation methods and iron-doping was forecasted.
