There are three crystal types of titania, namely, perovskite, anatase and rutile. Although in ceramic production knowledge, we think it is a coloring element, in fact, in nature, titanium dioxide is natural output is a relatively white mineral. The name of titanium dioxide indicates that it is white. The reason why titanium dioxide is considered as a coloring element in the production of ceramics is unfavorable to production, mainly because of the crystalline transformation of titanium dioxide at 800 degrees C, which turns into a color crystal, thus coloring. In our ceramic production, the temperature is often as high as more than 1000 degrees C, so the titanium dioxide in many industries has become an unfavorable factor in the ceramic industry.
In recent years, in the ceramic production process, at the very beginning, ceramic raw materials were basically taken precautions against iron and titanium elements to prevent coloring. However, some changes began to take place. Some ceramic companies began to relax the entry standards of titanium and titanium for the production of some products. For example, the iron content in feldspar is increased from 0.15% to 0.2~0.4%, and the content of titanium is enlarged from 0.1% to less than 0.2~0.3%. It is mainly considered that iron and titanium can react, and the color compounds produced are exactly the same for some products.
In addition, in the ceramic industry, titanium dioxide should have greater application space, enabling people to take the initiative to use titanium instead of titanium. This is the self cleaning product corresponding to titanium dioxide products. As the name suggests, a layer of titanium dioxide film is prepared on the surface of the ceramic product by reasonable technology. It can make the ceramic product self clean and suitable for the ceramic products of the exterior wall and toilet.
