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 ...
Alpha-beta-phase titanium has a mechanical property which is in between both. Titanium dioxide dissolves in the metal at high temperatures, and its formation is very energetic. These two factors mean that all titanium except the most carefully purified has a significant amount of dissolved oxygen, and so may be considered a Ti–O alloy. Oxide ...
Nevertheless, anatase is often the first titanium dioxide phase to form in many processes due to its lower surface energy, with a transformation to rutile taking place at elevated temperatures. [7] Although the degree of symmetry is the same for both anatase and rutile phases, there is no relation between the interfacial angles of the two ...

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
The oxidized form of the chlorine is molecular chlorine Cl 2, the reduced form is titanium tetrachloride (TiCl 4). The oxidizing agent is molecular oxygen (O 2), the reducing agent is coke. Both must be fed into the process. The titanium is fed into the process in form of ore together with the coke. Titanium ore is a mixture of oxides.
The solid is unstable with respect to loss of water and formation of titanium dioxide. Esters of orthotitanic acid are known, however; one example being titanium isopropoxide. Esters derived from smaller alcohols adopt more complex structures wherein titanium does achieve octahedral coordination, e.g. Ti 4 (OCH 3) 16 or titanium tetramethoxide. [4]
