Titanium dioxide is an inorganic compound with the chemical formula TiO2, and its appearance is white powder. It is non-toxic, best opacity, best whiteness and brilliance. TiO2 has many excellent properties, such as photocatalysis, semi-permanence, hydrophilicity, acid and alkali resistance, responsiveness to different visible light, weather resistance, and oxidation resistance. So titanium dioxide powder is widely used in plastics, coatings, paper, printing ink, chemical fiber, rubber, cosmetics and other industries. As an important white pigment and porcelain glaze, the amount of titanium dioxide accounts for more than 80% of all white pigments.
Difference Between Titanium Dioxide Rutile & Anatase Type
TiO2 titanium dioxide has two main structures: titanium dioxide rutile (R type) and titanium dioxide anatase (A type). They both have good chemical stability at room temperature and are insoluble in water, fat, most dilute acids and alkalis. However, in long-term outdoor environments, due to the more stable crystal structure of rutile titanium dioxide, it has a stronger ability to resist chemical erosion in the environment and its chemical stability is slightly better than that of anatase TiO2.
Rutile titanium dioxide has a compact structure, is relatively stable, and has low optical activity, so it has good weather resistance. At the same time, rutile TiO2 has high hiding power and color reduction power, so it is widely used in high-end fields such as coatings, plastics, inks, papermaking, rubber, chemical fibers, cosmetics, etc.
Compared with rutile titanium dioxide, anatase titanium dioxide has relatively lower hiding power and whiteness, but has good dispersibility and is easy to process. And anatase TiO2 is mainly used in low-end plastics, architectural coatings, paper and other fields.
The melting point of anatase titanium dioxide is as high as 1500℃, but under high temperature environment (above 400℃), it will gradually transform into rutile type and gradually turn yellow. While the melting point of rutile titanium dioxide is about 1850℃, and it has stronger thermal stability and is not prone to crystal transformation and color change at high temperature. By the way, As a leading supplier and exporter of titanium dioxide in China, Fengbai can supply these brands of titanium dioxide, such as Lomon, Billions, DONGFANG, PANGANG,etc.
