Titanium dioxide is the most commonly used titanium compound
About 95% of the titanium ore mined from the surface of the earth is sent to be refined into titanium dioxide (TiO2), an ultra-white long-lasting pigment that is used to make paint, paper, toothpaste and plastics. Titanium dioxide is also used in cement, gemstones, paper-making sunscreens, graphite composite fishing rods, and golf clubs.
Powdered TiO2 is chemically inert, does not fade in the sun, and is very opaque: these properties make it possible to bring a brilliant pure white color to the gray or brown chemicals used in the manufacture of household plastics. In nature, the compound of titanium dioxide can be found in several minerals such as anatase, brookite and rutile. Coatings made of titanium dioxide can withstand high temperatures, slightly prevent the accumulation of dust and dirt, and withstand the impact of the marine environment. The refractive index of pure titanium dioxide is very high, and the optical dispersion ability is higher than that of diamond. In addition to being a very important pigment, sunscreen oil also uses titanium dioxide, because it can protect the skin by itself.
Recently, it has also been used in air purifiers (filter coatings), and films attached to windows of buildings. This kind of film will have a height when exposed to ultraviolet rays (sun or artificial) or moisture in the air Active redox species, such as hydroxyl, can purify the air or keep the window surface clean.
