The building materials market, you can see a dazzling array of tiles in a variety of colors, and a variety of artistic patterns. More so, the gloss can even be comparable to jade. The raw materials for these tiles are very inconspicuous, and the main ingredient is clay, which is readily available everywhere. High-grade porcelain uses kaolin as a raw material, but since the output is very limited and the price is high, the ceramic tile is made of ordinary clay and is produced everywhere. Its main component is aluminum oxide, which is a common refractory material. After being fired, it can be transformed from a powder form to a complete whole, exhibiting a very high hardness and strength.
Because the heat resistance of clay is high, if you use this kind of raw materials, firing must reach a particularly high temperature, and this makes the cost to be unacceptable due to the fact that it will bring many technical problems. Therefore, the production of ceramic tiles requires the addition of another raw material, feldspar. It is also a very common mineral and it is very cheap. It is a relatively complex silicate and is alkaline. Because of its low melting point, it can also be used as a flux in ceramic tile materials. It can be fired at relatively low temperatures and can also enhance the ceramic tile toughness.
Quartz is silica, the most abundant mineral in the earth’s crust, and the main raw material for making glass. Pure quartz is crystal, with a crystal clear luster, and this advantage can also be reflected in the tile. When the firing is completed, the materials are combined into one piece and also have the appearance characteristics of glass, which can be polished to produce a beautiful gloss.
