Description
Product Description
Titanium dioxide (chemical formula: TiO₂) features stable chemical properties and barely reacts with most substances under normal conditions. In nature, titanium dioxide exists in three crystalline forms: brookite, anatase, and rutile. Brookite is an unstable crystalline form with no industrial application value. Anatase (abbreviated as Type A) and rutile (abbreviated as Type R), both with stable crystal lattices, are important white pigments and ceramic glazes. Compared with other white pigments, they boast superior whiteness, tinting strength, hiding power, weather resistance, heat resistance, and chemical stability—especially non-toxicity.
Titanium dioxide is widely regarded as the high-performance white pigment in the world currently. This product exhibits excellent characteristics such as high whiteness, high dispersibility, temperature and heat resistance, high hiding power, and good optical properties. Moreover, it possesses extremely good wettability, water dispersibility, compatibility, and fluidity when in water or high-concentration liquid environments. Additionally, this product is a primary rutile product without surface treatment (coating). Therefore, it is also an essential raw material for the subsequent coating treatment of rutile.
