Preparation method of red photonic crystal structured colored glaze

The invention discloses a preparation method of red photonic crystal structured colored glaze, which belongs to the technical field of ceramic glaze preparation. The preparation method comprises the following steps: 1) preparing anhydrous ethanol, ammonia water, water and ethyl orthosilicate in percentage by volume, and after the anhydrous ethanol, the ammonia water and the water are fully and uniformly mixed firstly, adding the ethyl orthosilicate into the obtained mixture, and stirring to have reaction to obtain SiO2 microsphere suspension liquid; 2) centrifuging the SiO2 microsphere suspension liquid, taking precipitates, and washing and drying the precipitates so as to obtain monodisperse SiO2 microspheres; 3) adding the monodisperse SiO2 microspheres into the anhydrous ethanol, carrying out ultrasonic dispersion so as to obtain a SiO2 microsphere emulsion; and 4) putting a ceramic substrate vertically into the SiO2 microsphere emulsion, carrying out vacuum drying until the anhydrous ethanol in the SiO2 microsphere emulsion is completely volatilized, and finally preparing a red photonic crystal structured colored glaze on the surface of the ceramic substrate. Because no pigment or coloring oxide is introduced, the method has the advantages of energy saving and environmental protection, has a broad application prospect, and can be applied to the preparation of red glaze for artistic ceramics, antique ceramics, floor and wall tiles and other ceramics.
