Uses: In cosmetic and skin care products, Titanium dioxide is used as a pigment, sunscreen and a thickener. It is also used as a tattoo pigment and in styptic pencils. Because of its brightness and very high refractive index (n = 2.7), Titanium dioxide is the most widely used white pigment. In ceramic glazes titanium dioxide acts as an opacifier and seeds crystal formation. Synthetic single crystals and films of Titanium dioxide are used as a semiconductor, and also in Bragg-stack style dielectric mirrors due to the high refractive index of TiO2 (2.5 – 2.9).

 

Titanium dioxide is often used to whiten skimmed milk which has been shown statistically to increase skimmed milk's palatability. Titanium dioxide is used to mark the white lines on the tennis courts of the All England Lawn Tennis and Croquet Club, best known as the venue for the annual grand slam tennis tournament The Championships, Wimbledon.

 

Titanium dioxide can be used to cleave protein that contains the amino acid proline at the site where proline is present. Titanium dioxide is also used as a material in the memristor, a new electronic circuit element. It can be employed for solar energy conversion based on dye, polymer, or quantum dot sensitized nanocrystalline TiO2 solar cells using conjugated polymers as solid electrolytes.

 

When you are using Titanium dioxide, you should be very cautious about it. This chemical may cause damage to health. It is harmful by inhalation, in contact with skin and if swallowed. In addition, it is irritating to eyes, respiratory system and skin. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. Whenever you will contact it, please wear suitable protective clothing.
