A tile is a flat plate-like clay-fired product made to cover the surface of the floor or wall of a building. Depending on the installed location and characteristics, the tile may be an internal tile, an exterior tile, a mosaic tile, Acid tiles, floor tiles, salt tiles, and query tiles.

Tiles have various performances, they are relatively easy to install, they do not cause cracking or discoloration after construction, and they are the best material to protect the surface of the structure because of its durability. Therefore, tiles are mainly used in kitchens, toilets, bathrooms and restrooms where hygiene is required in buildings.

Conventional indoor floor tiles are produced by milling inorganic raw materials such as clay, kaolinite, feldspar, and stones from a ball mill and then pressing and molding them, and then drying and sintering the products to form products by heating at about 1,170 ° C. It is nitrided and sintered so that it does not have the texture and function of natural soil and it is a simple building interior material for ordinary decoration.

Meanwhile, as a prior art related to the present invention, there is a method of preparing a tile by mixing and pulverizing slaked lime, clay, loess, silica, silica and the like, followed by hydrothermal synthesis. The above-described method has a problem in that the constituent raw materials are made of crystalline materials and the reactivity thereof is poor. Thus, there is a possibility that the color of the tile itself may be discolored due to the organic matter contained in the clay Big. In addition, there is a disadvantage in that when a contaminant is adhered to the surface of a product, aesthetic damage may occur due to absorption.
