A kind of preparation method of red photon glaze

Abstract

The invention relates to a preparation method of red photon glaze. The preparation method includes the steps that kaolin, quartz, TiO2, limestone, sodaclase, ZnO and talcum powder are adopted as raw materials, burdening, ball-milling, screening, decaying, drying, glazing, sintering and cooling are carried out, and then the product is obtained. According to the red photon glaze prepared with the method with a solid-phase sintering method, a photon-like crystal structure of the red photon glaze has higher density, thus, higher reflection efficiency is achieved for incident light, the method is simple in process, addition of heavy metal elements in tinting pigments is reduced, resource saving and environmental protection are benefited, the cost is low, large-scale production is easy, and therefore the preparation method has broad market prospects.

technical field [0001] The invention belongs to photonic crystal-like structure colored ceramic glazes, in particular to a preparation method of red photonic glazes. Background technique [0002] Photonic crystals refer to materials with photonic bandgap characteristics, which are periodically arranged on the optical scale. According to Bragg diffraction, a photonic bandgap of a certain size can be generated, and incident light with a corresponding wavelength size will be reflected and cannot continue to propagate.

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
