Titanium dioxide, an inorganic compound, chemical formula for TiO2, is a white solid or powdered amphoteric oxide, molecular weight 79.866, with non-toxic, the best opacity, the best whiteness and brightness, is considered to be the world's best performance of a white pigment. Titanium white has strong adhesion, is not easy to change chemically, and is always white. Widely used in coating, plastic, paper, printing ink, chemical fiber, rubber, cosmetics and other industries. It has a very high melting point and is also used to make refractory glass, glazes, enamel, clay, and high temperature resistant experimental vessels. Titanium dioxide can be extracted from rutile by acid decomposition or obtained from decomposition. Titanium dioxide exists in nature in three allotropic forms: rutile, anatase and plate titanium, in addition to several synthetic crystal forms.

Used in paint, ink, plastic, rubber, paper, chemical fiber and other industries; Used for welding rod, titanium refining and titanium dioxide manufacturing. Titanium dioxide (nano-scale) is widely used in functional ceramics, catalysts, cosmetics and photosensitive materials and other white inorganic pigments. It is one of the strongest white pigments, with excellent hiding power and color fastness, suitable for opaque white products. Rutile type is especially suitable for outdoor plastic products, which can give good photostability. Anatase type is mainly used for indoor products, but slightly blue light, high whiteness, large hiding power, strong coloring power and good dispersion. Titanium dioxide is widely used as paint, paper, rubber, plastic, enamel, glass, cosmetics, ink, watercolor and oil color pigment, can also be used in metallurgy, radio, ceramics, electrode
