Problems solved by technology

For example, in radiative cooling materials, photonic crystal layers are usually used to selectively transmit infrared radiation with a wavelength range of 8-13 μm, thereby achieving the effect of radiative cooling. However, the cost of this composite photonic crystal film is relatively high, and the preparation process is relatively complicated. , the mechanical properties are also poor

Abstract

The invention relates to a preparation method of black photon glaze. The preparation method includes the steps that kaolin, quartz, SrCO3, TiO2, limestone, BaCO3, sodaclase, ZnO, Pb3O4 and spodumene 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. The black photon glaze prepared with the method with a solid-phase sintering method can absorb or consume incident light of almost all wavebands, thus, energy emitted to a blank structure is reduced, and the temperature of a blank is remarkably reduced. 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.

Description

technical field [0001] The invention belongs to photonic crystal-like structural color ceramic glazes, in particular to a method for preparing black 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. Macroscopic Expressed as a saturated bright structured color. Another feature of photonic crystal materials is selective transmission, which can selectively transmit incident light of a specific wavelength. For example, in radiative cooling materials, photonic crystal layers are usually used to selectively transmit infrared radiation with a wavelength range of 8-13 μm, thereby achieving the effect of radiative cooling. However, the cost of this composite photonic...
