Titanium oxide

Artist's impression of the exoplanet WASP-19b, in which atmosphere astronomers 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.

Uses

Often used as an active ingredient in sunscreens combined with oxybenzone and octyl methoxycinnamate.^[4]

Also used in making of vehicle exhaust pipes due to its aesthetic value of the purple color.
