'''Titanium oxide''' may refer to:<ref>Wells A.F. (1984) ''Structural Inorganic Chemistry'' 5th edition Oxford Science Publications {{ISBN|0-19-855370-6}}</ref> * 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,<ref>{{Greenwood&Earnshaw}}</ref> e.g. Ti₃O₅, Ti₄O₇, 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.<ref name = "Wiberg&Holleman">{{Holleman&Wiberg}}</ref>

Ti₃O₅, Ti₄O₇, and Ti₅O₉ are non-stoichiometric oxides. These compounds are typically formed at high temperatures in the presence of excess oxygen.<ref>{{Cite journal |last1=Kumar |first1=Ashish |last2=Barbhuiya |first2=Najmul H. |last3=Singh |first3=Swatantra P. |date=2022-11-01 |title=Magnéli phase titanium sub-oxides synthesis, fabrication and its application for environmental remediation: Current status and prospect |url=https://www.sciencedirect.com/science/article/pii/S0045653522023712 |journal=Chemosphere |language=en |volume=307 |article-number=135878 |doi=10.1016/j.chemosphere.2022.135878 |pmid=35932919 |bibcode=2022Chmsp.307m5878K |s2cid=251339628 |issn=0045-6535|url-access=subscription }}</ref><ref name=":1">{{Cite journal |last1=Soleimani |first1=Meisam |last2=Ghasemi |first2=Jahan B. |last3=Badiei |first3=Alireza |date=2022-01-01 |title=Black titania; novel researches in synthesis and applications |url=https://www.sciencedirect.com/science/article/pii/S138770032100647X |journal=Inorganic Chemistry Communications |language=en |volume=135 |article-number=109092 |doi=10.1016/j.inoche.2021.109092 |s2cid=244769343 |issn=1387-7003|url-access=subscription }}</ref> 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.<ref name=":1" />
