改性钴蓝颜料及其研究进展

简述了尖晶石型钴蓝颜料的结构及其固相、液相、气相不同制备方法，通过XRD、SEM等测试手段从微观上总结了近年来不同价态离子掺杂对所制备出的钴蓝颜料结构和性能的影响，其中二价阳离子对颜料的晶格常数有明显影响，且晶格常数的变化符合Vegard定律；三价阳离子对颜料的色调有显著的改善。最后对从制备方法和掺杂离子方面对钴颜料的发展进行了展望。

Modified spinel-cobalt blue pigments and research progress

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.
