Abstract

The invention provides a vitrified tile and a preparation method of the vitrified tile and belongs to the technical field of ceramic. The vitrified tile provided by the invention is prepared from the following raw materials: Linyi porcelain stone, Mengyin feldspar, pyrophyllite, Zhucheng soil, quartz, alumina, Laiyang soil, soapstone, diopside and fat clay. All raw materials can take synergistic effect under the action of high temperature, the firing temperature can be reduced to some extent, the firing cycle is shortened, and the processing property and the physical and chemical properties of the product are qualitatively improved in comparison with a conventional process.

Description

technical field [0001] The invention belongs to the field of ceramic processing, and relates to a vitrified brick and a preparation method thereof. Background technique [0002] Vitrified bricks are one of the main products of architectural ceramics. Ceramic bricks with a water absorption rate of less than 0.5% are called vitrified bricks. Polished bricks with a water absorption rate of less than 0.5% are also vitrified bricks (higher than 0.5% can only be Polished tiles are not vitrified tiles), and then the vitrified tiles are mirror-polished to obtain vitrified polished tiles, because the water absorption rate is low and the hardness is relatively high, and it is not easy to scratch. At present, the most commonly used raw materials for vitrified bricks are feldspar and quartz. However, with the large-scale mining of these raw materials, the storage volume is getting smaller and smaller, and the quality is declining year by year. [0003] At present, the conventional firi...
