Problems solved by technology

Photonic crystal materials have excellent optical properties. Although the concept of photonic crystals has been proposed for more than 30 years, the research progress of photonic crystal structures in the field of ceramic glazes is relatively slow.
On the one hand, the glaze melt will undergo a strong chemical reaction during the sintering process, which increases the uncontrollability of the glaze layer structure; on the other hand, at high temperature, it is difficult to control the periodic regular arrangement of the crystal structure in the glaze layer
[0003] At present, the most widely used method for preparing photonic crystals is to use the self-assembly of colloidal particles in a sol-gel system to form photonic crystals, but the photonic crystals obtained through self-assembly have a low density and cannot exhibit bright and saturated structural colors. , and the sintering temperature required for the colloidal system is low, and the mechanical and optical properties of the obtained colloidal photonic crystal structure are low
The preparation of colloidal photonic crystals by the sol-gel method usually requires the use of some organic substances to prepare colloidal particle suspensions, which increases economic costs and is difficult to produce on a large scale

Abstract

The invention relates to a method for preparing a blue photon glaze. The method is characterized by including subjecting kaolin, quartz, TiO2, limestone, albite and ZnO powder which are adopted as rawmaterials to burdening, ball milling, sieving, ageing, drying, glazing, firing and cooling to obtain a product. The photon-like crystal structure of the photon glaze prepared by a one-step solid firing process has a higher degree of compactness so that a high reflection efficiency is achieved for incident light. The method is simple in process, reduces the addition of heavy metal elements in coloring pigment, and is beneficial to resource conservation and environmental protection. The method is low in cost and prone to large-scale production so that the method has a wide market prospect.
