Titanium Dioxide Uses

Titanium dioxide is a versatile compound used in a wide range of industries and applications. Its primary function is as a white pigment, offering brightness, whiteness, and opacity in various materials[1].

  • Paints and Coatings: Titanium dioxide provides whiteness, brightness, and opacity to paints and coatings, enabling excellent coverage and durability. Its UV resistance also helps protect surfaces from degradation[1][5].
  • Plastics and Rubber: TiO2 is used in plastics to improve color, heat resistance, light resistance, and mechanical properties. It helps plastics and rubbers maintain stability and durability, especially in outdoor environments[2][3][5].
  • Cosmetics and Personal Care: In cosmetics, titanium dioxide acts as a pigment and a UV filter, making it essential in foundations, powders, and most notably, sunscreens, where its natural UV-blocking properties protect the skin[1][3][5].
  • Food and Pharmaceuticals: In foods, it is used as a whitening agent for products like candies, dairy items, and coffee creamers. In pharmaceuticals, it coats tablets and capsules and is included as a coloring agent in supplements[1][3][5].
  • Paper and Printing Inks: TiO2 is added to paper to enhance whiteness and opacity and to printing inks for brilliant coloration[2][5].
  • Textiles and Fabrics: It is utilized in textiles and coated fabrics to impart brightness and UV stability[5].
  • Ceramics, Floor Coverings, and Roofing: Titanium dioxide offers whiteness, durability, and resistance to weather and sunlight in ceramics, tiles, and roofing materials[5].
  • Water Treatment: Some applications use TiO2 as a photocatalyst to break down organic pollutants, help sterilize water, and remove bacteria and viruses[7][4].
  • Automotive Products and Catalysts: It is found in automotive greases, engine oils, and as a component in catalysts[3][5].

About 94% of all titanium extracted globally is used to produce titanium dioxide, highlighting its industrial importance[4].
