Technical Field

The invention relates to the technical field of ceramic material manufacturing, in particular to a high-saturation amorphous photon structure colored glaze and a preparation method thereof.

Background

The color and decoration of the ceramic glaze layer are based on pigments introduced in the glaze, but the pigments are complex in preparation process, high in energy consumption and serious in pollution, and become a great obstacle to the green sustainable development of the ceramic industry. Compared with the traditional pigment, the structural color avoids environmental pollution caused by using a chemical pigment, can be never faded as long as the integrity of the micro-nano structure is kept, and has the characteristics of environmental protection, high brightness, high saturation and the like. Therefore, in the field of ceramic decoration, the structural color is used for replacing the traditional coloring material to generate color, so that the ceramic decoration has wide application prospect.

According to different sources of the structural color, the structural colored glaze can be divided into amorphous photon structural colored glaze and structural colored glaze formed by Rayleigh scattering and Mie scattering. As the amorphous photon structure has the characteristics of isotropic photonic band gap, non-iridescence effect, light localization and the like, the ceramic glaze is soft and bright and has a color rendering effect which is not changed along with the angle, and the ceramic glaze has a wider application space in the field of ceramic decoration (material guide, 2017,31(1): 43-55). However, in the amorphous photonic structure colored glaze, the color saturation of the structural color formed by Bragg scattering is reduced due to the influence of incoherent scattering (Advanced Materials,2018,30(28):1706654), and the color visibility is not strong, so that the wide application of the amorphous photonic structure colored glaze in the ceramic industry is limited.
