Widely used as a white pigment in paints, coatings, and plastics due to its high opacity and brightness. Common in cosmetics like sunscreens and foundations because it effectively scatters and reflects UV light, offering protection without chemical irritation. Employed in photocatalytic applications, such as self-cleaning surfaces and air purification systems, where it breaks down organic pollutants under UV light. Also used in dye-sensitized solar cells and as a coating material in medical implants for its biocompatibility and resistance to corrosion.
