Titanium oxide

Artist's impression of the exoplanet WASP-19b, in which atmosphere astronomers, including Nikku Madhusudhan, detected titanium oxide.^[1]

Titanium oxide may refer to:^[2]

Titanium dioxide (titanium(IV) oxide), TiO₂
Titanium(II) oxide (titanium monoxide), TiO, a non-stoichiometric oxide
Titanium(III) oxide (dititanium trioxide), Ti₂O₃
Ti₃O
Ti₂O
δ-TiO_x (x= 0.68–0.75)
Ti_nO_2n−1 where n ranges from 3–9 inclusive,^[3] e.g. Ti₃O₅, Ti₄O₇, etc.

Reduced titanium oxides

[edit ]

A common reduced titanium oxide is TiO, also known as titanium monoxide. It can be prepared from titanium dioxide and titanium metal at 1500 °C.^[4]

Ti₃O₅, Ti₄O₇, and Ti₅O₉ are non-stoichiometric oxides. These compounds are typically formed at high temperatures in the presence of excess oxygen.^[5]^[6] As a result, they exhibit unique structural and electronic properties, and have been studied for their potential use in various applications, including in gas sensors, lithium-ion batteries, and photocatalysis.^[6]
