Titanium dioxide, also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə /, is the inorganic compound derived from titanium with the chemical formula TiO 2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. [4] It is a white solid that is insoluble in water, although mineral forms can appear ...

When titanium dioxide is exposed to ultraviolet radiation from sunlight, it absorbs the radiation and electron excitation occurs. The following reactions then occur on the surface of the titanium dioxide crystals: Photolysis of water: H 2 O → H + + OH (hydroxyl radical) + e − O 2 + e − → O 2 − (a superoxide ion) The overall reaction ...
Titanium dioxide is the most commonly used compound of titanium. About 95% of all titanium ore is destined for refinement into titanium dioxide (TiO 2), an intensely white permanent pigment used in paints, paper, toothpaste, and plastics. [31] It is also used in cement, in gemstones, and as an optical opacifier in paper. [98] TiO

They are commonly utilized for their catalytic activity and semiconducting properties. Transition metal oxides are also frequently used as pigments in paints and plastics, most notably titanium dioxide. Transition metal oxides have a wide variety of surface structures which affect the surface energy of these compounds and influence their ...

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
