Titanium Oxide

Definition - What does Titanium Oxide mean?

Titanium oxide refers to:

  • Titanium dioxide (TiO2 or titanium IV oxide)
  • Titanium (II) oxide, also known as titanium monoxide (TiO is also known as a non stoichiometric oxide)
  • Titanium (III) oxide, also known as di-titanium trioxide (Ti2O3)
  • Ti3O
  • Ti2O

Titanium is the fourth most abundant metallic element in the earth’s crust and occurs chiefly as an oxide ore.

Corrosionpedia explains Titanium Oxide

Titanium oxides are used to provide surface protection to titanium alloys.

In most aqueous environments, the oxide is typically TiO2, but may consist of mixtures of other titanium oxides, including Ti2O3 and TiO.

High-temperature oxidation promotes the formation of the chemically resistant, highly crystalline form of TiO, known as rutile, whereas lower temperatures often generate the more amorphous form of TiO, anatase, or a mixture of rutile and anatase.

Titanium oxide is highly chemically resistant and is attacked by very few substances, including hot, concentrated HCl, H2SO4, NaOH, and (most notably) HF. This thin surface oxide is also a highly effective barrier to hydrogen.
