Abstract

The invention relates to a crystal glaze ceramic tile and a production method thereof. The method comprises the following steps: distributing a crystal clinker and seed crystal on a conventional ceramic tile blank, heating to 1130-1200 DEG C, and insulating for 10-30 minutes; then, cooling to 1000-1080 DEG C, and insulating at the temperature for 1-2 hours to prepare the crystal glaze ceramic tile with a remarkable crystal flower effect. An artistic decoration effect with large and round crystal flower and diversified patterns and colors can be achieved by utilizing the crystal glaze ceramic tile; a crystal glaze ceramic of which flowing stripes are arranged on the surface, and an artistic aesthetic value can be remarkably increased. When the crystal clinker is prepared, the smelting temperature is low, and the smelting time is short; when the crystal glaze ceramic tile is fired, the firing temperature is low, and the required crystallization time is short, so that the production energy consumption is remarkably reduced, the firing cycle is shortened, the production cost is reduced, the waste emission amount in the production process is reduced, and excellent economic and social benefits can be brought.

Description

technical field [0001] The invention relates to the technical field of production methods of artistic ceramic tiles, in particular to a crystal glazed ceramic tile and a production method thereof. Background technique [0002] Crystalline glaze is a kind of artificial crystal flower glaze used to decorate and display ceramics, daily-use ceramics and other products. It is developed on the basis of Chinese ancient glaze. In the Song Dynasty, on the basis of color glazes, redox atmosphere was used to manufacture kiln-changing flower glazes. Some of the color glazes naturally presented gorgeous and colorful microcrystals, such as Tianmu, Xingzhan, tea powder, iron embroidery, grape spots, sesame spots, etc. Microcrystalline crystalline glaze is considered to be the earliest crystalline glaze product in the world. [0003] However, the large-scale application of crystal glaze to architectural ceramic decoration is still a technical bottleneck that is difficult to break through. ...
