Titanium dioxide is mainly composed of white pigment of titanium dioxide (TiO2). The scientific name is titanium dioxide, the molecular formula of TiO2 is a polycrystalline compound, the particle is in a regular arrangement with lattice structure. The relative density of titanium dioxide is the smallest.

　　Titanium dioxide is considered to be the world's best performance of a white pigment, widely used in coatings, plastics, paper, printing inks, chemical fiber, rubber, cosmetics and other industries.

　　Titanium dioxide (titanium dioxide) is chemically stable and in general does not react with most substances. In nature, there are three kinds of crystal titanium dioxide: Plate titanium, anatase and rutile. Plate titanium type is unstable crystal type, no industrial use value, Anatase (anatase) abbreviation Type A, and rutile (rutile) abbreviation R type, all have a stable lattice, is important white pigments and porcelain glaze, compared with other white pigments have superior whiteness, coloring force, hiding power, weather resistance, heat resistance, and chemical stability, especially without toxicity.

　　Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemical, medicine, food and other industries.
