Titanium oxide

Titanium oxide may refer to:

  • Titanium dioxide (titanium(IV) oxide), TiO<sub>2</sub>
  • Titanium(II) oxide (titanium monoxide), TiO, a non-stoichiometric oxide
  • Titanium(III) oxide (dititanium trioxide), Ti<sub>2</sub>O<sub>3</sub>
  • Ti<sub>3</sub>O
  • Ti<sub>2</sub>O
  • δ-TiO<sub>x</sub> (x= 0.68–0.75)
  • Ti<sub>n</sub>O<sub>2n−1</sub> where n ranges from 3–9 inclusive, e.g. Ti<sub>3</sub>O<sub>5</sub>, Ti<sub>4</sub>O<sub>7</sub>, etc.

Reduced titanium oxides

A common reduced titanium oxide is TiO, also known as titanium monoxide. It can be prepared from titanium dioxide and titanium metal at 1500&nbsp;°C.

Ti<sub>3</sub>O<sub>5</sub>, Ti<sub>4</sub>O<sub>7</sub>, and Ti<sub>5</sub>O<sub>9</sub> are non-stoichiometric oxides. These compounds are typically formed at high temperatures in the presence of excess oxygen. 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.
