Titanium dioxide (chemical formula: TiO2), the white solid or amphoteric oxide powder, molecular weight: 79.83, is a kind of white pigment, with non-toxic, best best whiteness and brightness, opacity, was considered the performance of the best in the world at present a kind of white pigment.Titanium white adhesive force strong, not easy to change chemical change, always be snow-white.It is widely used in coatings, plastics, papermaking, printing ink, chemical fiber, rubber, cosmetics and other industries.It has a high melting point and is used to make refractory glass, glaze, enamel, clay, and high temperature test ware. At the same time, the titanium dioxide has good ultraviolet masking effect, often used as a sunscreen in the textile fiber, ultrafine titanium dioxide powder were joined into the sunscreen cream made from sunscreen cosmetics.
