Photochromic Jun glaze and preparation method thereof

Abstract

The invention provides photochromic Jun glaze and a preparation method thereof. The photochromic Jun glaze is prepared from raw materials in parts by weight as follows: 13-19 parts of melilite, 25-31parts of quartz, 9-15 parts of calcite, 2-4 parts of Suzhou clay, 17-23 parts of glarizonae, 13-19 parts of nano-tungsten oxide, 1.5-2.5 parts of nano-titanium oxide and 0.5-1.5 parts of nano-zinc oxide. The photochromic Jun glaze has the photochromic function, fewer air holes are formed in the glaze surface, the phenomenon of sagging is eliminated, the jade texture is great, and rate of finishedproducts is high.

Description

technical field [0001] The invention relates to the technical field of glazes, in particular to a photochromic enamel glaze and a preparation method thereof. Background technique [0002] Jun Porcelain is one of the five famous kiln porcelains in Song Dynasty in my country. The secret of "kiln transformation" lies in its glaze firing mechanism. The composition of Jun porcelain glaze is complex. During the glaze firing process, slight changes in the temperature and atmosphere in the kiln may trigger different chemical reactions, and promote the ever-changing color of Jun porcelain. . In the case of strictly controlling the temperature and atmosphere of glaze firing, the colorants in the glaze play a decisive role in the color development, and the most commonly used colorants are oxides such as copper oxide and iron oxide. The color is fixed. Although this kind of glaze is very beautiful, it can no longer satisfy people's pursuit of a higher level of Jun porcelain art. There...

Problems solved by technology

In the case of strictly controlling the temperature and atmosphere of glaze firing, the colorants in the glaze play a decisive role in the color development, and the most commonly used colorants are oxides such as copper oxide and iron oxide. The color is fixed. Although this kind of glaze is very beautiful, it can no longer satisfy people's pursuit of a higher level of Jun porcelain art. Therefore, it is imminent to study new functional Jun porcelain glazes. At present, the research on functional glazes The research mainly focuses on the color-changing glaze. The color-changing enamel glaze is prepared by adding the color-changing glaze into the Jun porcelain glaze, so that it can show different color effects under different light sources. However, the photochromic glaze currently fired The yield of the material is low, and the stability of the photochromic powder is poor at high temperature, and it cannot exist stably
