Chemical Appearance

– Titanium dioxide manifests as a white, opaque powder or pigment.

Applications:

Titanium dioxide serves various purposes in different industries:

– Paints and Coatings: It actively contributes to the opacity and brightness of – paints and coatings, enhancing their covering ability.

– Cosmetics: In cosmetics, it acts as a white pigment in products such as sunscreens, foundations, and powders.

– Plastics and Polymers: It imparts whiteness and opacity to plastics, making them more visually appealing.

– Paper: Used in the paper industry to enhance the brightness and opacity of paper products.

– Food and Pharmaceuticals: Approved as a food additive, it provides whiteness in products like toothpaste, candies, and pharmaceutical tablets.

– Photocatalysts: Utilized in photocatalytic applications for its ability to accelerate certain chemical reactions when exposed to light.

– Ceramics: Used in the ceramic industry to achieve desired colors and textures in glazes.

– Textiles: Incorporated into textiles for its UV-blocking properties and ability to enhance fabric whiteness.

– Photovoltaic Cells: Applied in solar cells to improve light absorption and energy conversion efficiency.
