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]

Used to give the white colour of titanium white paint.
