Introduction to the production method of porcelain tile
As a commonly used decoration material, porcelain tile are commonplace for us, but do you know what materials are made of porcelain tile? The following editor will learn with you what materials are used for porcelain tile.

When it comes to porcelain tile production, we have to start with the traditional porcelain tile production. Traditional porcelain tile production generally requires selection of materials, ingredients, raw material processing, molding, baking, glazing and high-temperature calcination at 1200-1300°C. In addition, in addition to the above steps, polished tiles need to be polished, edged, inspected, graded, and packaged before they can be finished. Most of the raw materials required in the porcelain tile production process are metal oxides. Among them, there are three important oxides: clay, powdered quartz and feldspar.

So, what are the functions of these three oxides? Clay can make ceramics more plastic, so that people can make them into ideal shapes before heating. The powdered quartz is generally extracted from quartzite, sand or rock. It is added to porcelain tile as a filler to make the product have ideal performance. Feldspar is a broad genus name of alkaline aluminosilicate, which mainly acts as a "fluxing agent", just like a bonding element that increases the strength of the ceramic body.
In addition to the raw materials mentioned above, we also use a large number of other natural minerals and some synthetic chemical raw materials in our production. Among the more important raw materials are: chalk powder: namely calcium carbonate, tin oxide, magnesium carbonate, barium titanate (barium oxide-titanium oxide), talc, lead zirconate (lead oxide-zirconium oxide), nepheline syenite, Iron oxide, zircon, silicon carbide, anhydrous borax, barium carbide, pyrophyllite, boron nitride, spodumene, cobalt oxide, beryl, etc.
