尖晶石型钴蓝颜料的研究进展

Research progress of spinel-cobalt blue pigment

介绍了尖晶石型钴蓝颜料的结构和显色机理,结合纳米材料的制备方法,综述了近年来钴蓝颜料制备方法及工艺,主要有固相反应法、液相反应法、气相法。其中固相反应法生产工艺简单,是目前工业生产常用方法,但制备的颜料粒径、色泽、稳定性等性能不能充分满足市场需求;液相反应法与气相法均可制成高品质的钴蓝颜料,但工艺复杂、成本较高。最后对钴蓝颜料的应用和发展作了简要介绍。

In this paper the structure and coloration mechanism of spinel cobalt blue pigments are introduced. Recent research progress of synthesis methods and technologies of cobalt blue pigment are summarized, in terms of the preparation methods of nano-materials. These processes include solid phase reaction process, liquid phase reaction process and gas phase process. The solid phase reaction process is commonly used in industry because of its simple technology, but the particle size, color, stability of pigment can not fully meet the market demand. High quality cobalt blue pigments can be prepared by the liquid phase reaction process or gas phase process, but both processes are complex and expensive. The research directions and application prospects of cobalt blue pigments are also presented.
