Titanium dioxide (chemical formula: TiO2, white solid or powdered amphoteric oxide, molecular weight: 79.9, is a white inorganic pigment with non-toxic, best opacity, best whiteness and brightness, and is considered to be the world A white pigment with the best performance. Titanium white has strong adhesion and is not easy to undergo chemical changes. It is always white. It is widely used in coatings, plastics, papermaking, printing inks, chemical fiber, rubber, cosmetics and other industries. Very high, it is also used to make refractory glass, glaze, enamel, clay, high temperature laboratory utensils, etc.

Titanium dioxide 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
