Problems solved by technology

[0004] However, while people are pursuing nobility and elegance, golden yellow is often the most distinctive and represents nobility, but there is little research on light-changing glazes in this regard
[0005] In addition, during the firing process of ceramic products, the heating time is too fast (generally within 1-1.5 hours to the firing temperature), and the holding time is too short (generally 20-40 minutes), which will lead to uneven glaze. , affect the reflective effect, thus affecting the quality of ceramic products

Abstract

The invention discloses a photochromic glaze, a preparation method thereof and a preparation method of photochromic ceramic products, belonging to the technical field of porcelain product glazes. A photochromic glaze, comprising the following raw materials in parts by weight: 6-9 parts of kaolin, 40-48 parts of feldspar, 20-26 parts of quartz, 5-10 parts of glass powder and 5-7 parts of calcined oxide; Calcined oxide is to dissolve 1-3 parts of manganese dioxide and 12-15 parts of ferric oxide mixture in 8-25 parts of water, and then perform ball milling for 10-15 hours, and the temperature of the ball-milled product is raised to 5°C / min. It is obtained by calcination at 600~800℃ for 6~8 hours and then cooling to room temperature naturally. The surface layer of the illuminated glaze of the present invention is smooth and smooth, and changes from brown to golden yellow under light, and the mark at the bottom mark is a three-dimensional pattern, which is noble and unique, thereby improving the appearance quality of ceramic products.

Description

technical field [0001] The invention belongs to the technical field of ceramic products, and in particular relates to a photochromic glaze, a preparation method thereof, and a preparation method of photochromic ceramic products. Background technique [0002] With the improvement of people's quality of life and the change of consumption concept, ceramic products are required to be practical, artistic and ornamental. In order to improve the practicability, artistry and appreciation of ceramic products, it is often necessary to work hard on the glaze, which is realized by adopting a special glaze formula to make porcelain products with different color rendering surfaces. [0003] CN 200910047570.5 discloses a rare-earth ceramic glaze pigment that can change color under different light sources, which is composed of 17-29% by weight of color-changing neodymium red pigment and 83-71% of feldspar glaze; wherein the weight composition of color-changing neodymium red pigment For: Si...
