Titanium dioxide is an inorganic, chemical formula TiO2, white solid or powdered amphoteric oxide, molecular weight 79.9, has non-toxic, optimal opacity, optimal whiteness and brightness, is considered to be the best in the world today A white pigment. Titanium white adhesion is strong, not easy to chemically change, always be white. Widely used in coatings, plastics, paper, printing ink, chemical fiber, rubber, cosmetics and other industries. Its melting point is high, and it is also used to make refractory glass, glaze, enamel, clay, high temperature resistance experimental vessel.

At the same time, the titanium dioxide has a good ultraviolet masking, often incorporated into the textile fiber as a sunscreen, and ultrafine titanium dioxide powder is also entered into sunscreen cream into sunscreen cosmetics.

Titanium dioxide can be extracted from acid-red with acid or divided by titanium tetrachloride. Titanium dioxide is stable, a large number of white pigments used as paint, which has good concealed ability, similar to the white, but unlike a lead white; it has the same persistence as zinc. Titanium dioxide is also used as an enamel extract agent, which can produce a very bright, hard and acid-resistant enamel enamel surface.

Titanium dioxide generally sharp titanium mineral (ANATASE, referred to as a type) and rutile type (RUTILE, referred to as R-type)
