Problems solved by technology

At present, there are many types of surface glazes in production. For example, the tiles of the prior art have different requirements for the frit in the glazing procedure, and the performance of the glaze is different. The amount of glaze must have a certain thickness. , poor thermal stability, easy to produce color difference, easy to deform the product, small scope of application, poor high temperature fluidity, resulting in rough glaze, poor antifouling performance, low yield, etc. In addition, the transparency and smoothness of the product need to be further improved space

Abstract

The invention discloses a transmutation overglaze. The overglaze comprises the following components in percentage by mass: 70%-75% of frit, 5%-8% of kaolin, 4.5%-6.5% of zinc oxide, 1.2%-2.5% of barium carbonate, 4.5%-6% of titanium dioxide, 2.5%-4.5% of bone meal, 1%-2% of ferric oxide and 1%-2% of cobalt oxide. The invention further discloses a preparation method of the transmutation overglaze and porcelain. According to the transmutation overglaze and the preparation method thereof and the porcelain in the invention, the preparation method of the transmutation overglaze is simple in production process and low in environmental pollution; a unique overglaze formula is adopted, and through mutual cooperation and combined action of all the components and the content of the components, the overglaze is transparent and smooth in surface, good in glaze slip performance and good in firing performance; and an overglaze porcelain product is good in decorative effect, fine and smooth in glazesurface and good in texture. The invention belongs to the technical field of ceramics.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a kiln-transformed glaze, a preparation method thereof, and porcelain. Background technique [0002] Top glaze is a layer of enamel covering the surface or bottom glaze of ceramic products in the manufacturing process of ceramic products, which can resist corrosion and increase the decorative effect of products. At present, there are many types of surface glazes in production. For example, the tiles of the prior art have different requirements for the frit in the glazing procedure, and the performance of the glaze is different. The amount of glaze must have a certain thickness. , poor thermal stability, easy to produce color difference, easy to deform the product, small scope of application, poor high temperature fluidity, resulting in rough glaze, poor antifouling performance, low yield, etc. In addition, the transparency and smoothness of the product need to be further improve...
