Titanium dioxide (TiO₂) is a white, opaque inorganic pigment renowned for its exceptional brightness, opacity, and UV resistance. It is extensively used in paints, coatings, plastics, and inks to ensure superior coverage and long-lasting durability.
Properties:
- UV Absorption: It absorbs and reflects ultraviolet (UV) light, protecting from UV rays in sunscreens and coatings.
- Chemical Stability: It is a stable, non-toxic, and inert material, making it suitable for various applications.
Applications:
- Pigment: A major use is as a white pigment in paints, plastics, paper, and inks, providing excellent coverage and color.
- Cosmetics & Sunscreens: It’s used in sunscreens and cosmetic products to provide UV protection and impart whiteness.
- Food Coloring: Food-grade TiO₂ is used to enhance the color and brightness of various food products.
- Self-Cleaning Surfaces: TiO₂’s photocatalytic properties enable self-cleaning and air purification in coatings and textiles.
- Gas Sensors: Its ability to change electrical resistance when interacting with gases allows it to function as a gas sensor
- Biomedical Applications: It holds promise in cancer treatment through photodynamic and photothermal therapies and for advanced medical imaging.
