Titanium dioxide in the anatase form is used as a white pigment in paints, coatings, plastics, printing inks, and paper manufacturing, where it provides good brightness and opacity, though less than the rutile form. It offers excellent UV-blocking properties, making it suitable for sunscreens, foundations, and cosmetic powders due to its non-irritating nature. Anatase is particularly valued as a photocatalyst in environmental applications, such as self-cleaning surfaces, air purification systems, and water treatment, where it breaks down organic pollutants under UV light. Its semiconductor characteristics also make it useful in dye-sensitized solar cells and other energy applications.
