Problems solved by technology

[0003] On the other hand, because the overglaze color is glazed on the surface of the ceramic product after high-temperature firing, the surface of the high-temperature fired ceramic product is relatively smooth, does not absorb water, and the color material is not easy to absorb, which leads to the surface of the over-glaze color product being easy to absorb. Disadvantages such as uneven glaze application and easy fall off of colored glaze have seriously affected the appearance quality of the product

Abstract

The invention relates to a glazed low-temperature bright-red glaze and a production process for ceramic products thereof, and belongs to the technical field of ceramics. The glazed low-temperature bright-red glaze is prepared by mixing 40 to 45 weight percent of bright-red pigment and 55 to 60 weight percent of low-temperature clinker, wherein the low-temperature clinker comprises the following components in percentage by weight: 1.2 to 2.4 percent of Li2O, 6.3 to 7.7 percent of KNaO, 43.1 to 46.2 percent of SiO2, 0.03 percent of Fe2O3, 4.9 to 6.9 percent of Al2O3, 4.9 to 5.6 percent of CaO, 27.2 to 28.9 percent of B2O3, 3.6 percent of SrO, 1.0 percent of ZrO and 1.2 to 1.6 percent of F. The production process for the ceramic products of the glazed low-temperature bright-red glaze comprises the following steps of: preparing the glaze, adding a deflocculating agent and water, mixing uniformly, performing ball milling, sieving, glazing, drying in the shade, and roasting. The technology is easy to implement; and the products have the characteristics of firm combination of blanks and the glaze, bright colors, high gloss and hardness, no toxin and the like.

Description

technical field [0001] The invention relates to a production process of an on-glaze low-temperature brilliant red glaze and ceramic products thereof, belonging to the technical field of ceramics. Background technique [0002] At present, overglaze coloring is a decoration method widely used in ceramic products. The traditional overglaze color production process is to add 30-50% lead oxide, so that the firing temperature range of the ceramic overglaze pigment is wide and the color is pure. However, lead is harmful to the environment and human body during the production and use of ceramic pigments. Therefore, many research and development institutions and manufacturers are trying to find an additive that can replace lead oxide, and at the same time make ceramic glazes have the characteristics of low firing temperature and bright color. At present, there have been the use of Bi 2 o 3 The advantages of low melting point instead of lead oxide. But bismuth is also toxic, and ...
