Application of cobalt niobate-based material in blue pigment, blue glaze and preparation method of blue glaze
The invention provides application of a cobalt niobate-based material in a blue pigment, a blue glaze surface and a preparation method of the blue glaze surface, and relates to the technical field of inorganic pigments. The invention provides an application of a cobalt niobate-based material in a blue pigment, the chemical formula of the cobalt niobate-based material is Co < 1-x > M < x > Nb < 2 > O < 6 >, and M is one of Mg, Ca, Zn, Sr and Ba; and x is 0-1. In the cobalt niobate-based material provided by the invention, the crystal structure where Co < 2 + > is located and the coordination thereof have strong influence on the coloring strength and hue of the pigment, Co < 2 + > is located at a distorted octahedral position point, a visible light region absorption band is mainly located in red, orange and yellow light regions, most of visible light in a blue wave band can be reflected, and pure blue can be displayed; meanwhile, Nb < 5 + > has a higher valence state, so that the color generation stability of the pigment in glaze can be enhanced, and the pigment can be applied to a medium-high temperature environment of 600-1200 DEG C.
本发明提供了一种铌酸钴基材料在蓝色色料中的应用、蓝色釉面及其制备方法，涉及无机色料技术领域。本发明提供铌酸钴基材料在蓝色色料中的应用，所述铌酸钴基材料的化学式为：Co1‑xMxNb2O6，其中M为Mg、Ca、Zn、Sr和Ba中的一种；x为0～1。本发明提供的铌酸钴基材料中，Co2+所在的晶体结构及其配位对色料的着色强度和色调有强烈影响，其中Co2+处于扭曲的八面体位点，可见光区吸收谱带主要位于红、橙、黄三个光区，能反射大部分蓝色波段的可见光，可显示出纯正的蓝色；同时，Nb5+具备更高的价态，能够增强色料在釉料中的呈色稳定性，可应用于600～1200℃的中高温环境。
