Titanium Dioxide (TiO2)-Powder

Characteristic

Titanium dioxide (chemical formula: TiO2), the white solid or amphoteric oxide powder, molecular weight: 79.9, is a kind of white pigment, with non-toxic, best best whiteness and brightness, opacity, is considered to be today's performance is one of the best white pigment in the world. Titanium dioxide adhesion is strong, not easy to chemical changes, is always white. Titanium dioxide is generally divided into Anatase (A) and Rutile (R).
