Properties: Titanium Dioxide

Two main types of titanium dioxide are used industrially, rutile and anatase. Due to poor mechaincal properties they are generally used for optical properties as pigments for paints, plastics, ceramic glazes and enamels etc. Other uses include oxygen sensors, photovoltaics and antimicrobial coatings

Thermal and physical properties of titanium oxide at high pressure

Titanium dioxide has two interesting properties. When water comes in contact with TiO 2 under the influence of light irradiation, it forms an extremely small contact angle ( ≈ 0°) with water. Materials having this property of superhydrophilicity can defog glass, and it can also enable oil spots to be wiped away easily with water.
