Abstract

The invention provides a ground glaze suitable for quick firing of a glazed tile. The ground glaze comprises the following components by mass percentage: 27-35% of potash feldspar, 8-14% of albite, 1-4% of calcined talc, 2.5-4.8% of a medium temperature frit, 0.5-2.2% of a high expansion frit, 20-35% of quartz, 10-14% of kaolin, and 7-15% of calcined alumina. In addition, the invention also provides a glazed tile containing the ground glaze. According to the formula design of the ground glaze provided by the invention, the dosages of the quartz and calcined alumina are increased simultaneously, firstly the color development effect and firing temperature of the formula are improved, and then the method of adding the medium temperature frit is adopted to realize the purpose of formula cooling, thus not only broadening the firing range of the glazed tile, meeting the requirement of quick firing, but also reaching a good color development effect.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to an underglaze suitable for rapid firing of glazed tiles, glazed tiles and a preparation method thereof. Background technique [0002] Full-glazed products are one of the main products in architectural ceramics. They have rich patterns and colors. Since the glaze color pattern is between a layer of transparent glaze, the pattern and color will not decrease due to the increase of time during use. Light phenomenon, so sought after by consumers. [0003] At present, in the production process of glazed tiles, there are problems such as poor glaze bonding, narrow firing range, and strict firing requirements. For this problem, the existing adjustment method generally solves it by reducing the content of calcined alumina and increasing the content of quartz; however, this solution makes the firing temperature range of glazed tiles narrow and the product quality is unstable;...
