The Chemical Formula of Titanium Dioxide and Its Suppliers

Titanium dioxide, also known by its chemical formula TiO2, is a versatile compound with a wide range of applications across various industries. Most commonly recognized for its role as a pigment, titanium dioxide is prized for its brightness and opacity. It serves various functions, from providing whiteness in paints and coatings to acting as a UV filter in sunscreens. Understanding its chemical composition and the suppliers that provide this essential material can facilitate better choices in application and sourcing.

Chemical Composition of Titanium Dioxide

The chemical formula TiO2 indicates that titanium dioxide consists of one titanium atom and two oxygen atoms. This simple, robust structure gives rise to titanium dioxide's unique properties, such as high refractive index and strong UV light absorption. Predominantly, titanium dioxide exists in three crystalline forms anatase, rutile, and brookite, with the first two being the most commercially important. Rutile is the more stable form and is often used in the production of pigments, while anatase is favored for specific photocatalytic applications due to its greater surface area.

These forms of titanium dioxide exhibit different optical and chemical characteristics. Rutile is known for its superior durability and is often used in outdoor applications where resistance to weathering is essential. Conversely, anatase is commonly employed in applications requiring photocatalytic efficiency, such as self-cleaning surfaces and environmental applications.

Applications of Titanium Dioxide

Due to its excellent light-scattering properties, TiO2 is extensively used as a white pigment in various products, including

1. Paints and Coatings Its ability to provide excellent coverage and durable finish makes titanium dioxide essential in the paint industry, particularly for exterior applications. 2. Plastics When used in plastics, TiO2 enhances opacity and durability, making it valuable in the manufacturing of consumer products, packaging materials, and automotive components.

3. Cosmetics In cosmetics, titanium dioxide acts as a pigment in foundations, powders, and sunscreens, providing a barrier against UV radiation and helping achieve desired cosmetic effects.

4. Food Industry Titanium dioxide is utilized as a food additive, designated as E171, primarily used to enhance the whiteness of various food products.

5. Photocatalysis In environmental applications, titanium dioxide plays a pivotal role in photocatalytic processes for air and water purification, breaking down pollutants when exposed to UV light.
