What Does Titanium Oxide Mean?
Titanium oxide refers to any naturally or artificially occurring chemical compound that comprises of oxygen and titanium as its only two elemental constituents. Examples of titanium oxide compounds are TiO and Ti2O3.
Titanium compounds are typically very corrosion resistant, making them ideal for construction and industrial applications.
Corrosionpedia Explains Titanium Oxide
Due to the highly corrosion resistant nature of titanium oxides, they are often used as surface protection to metallic alloys. In most aqueous or seawater environments, the oxide used is typically TiO2.
Titanium oxide is also highly chemically resistant and attacked by very few substances. Its resistance to particularly strong acids, such as concentrated HCl, H2SO4, and HF make it an ideal protective layer for metals used in chemical production equipment. Unlike other oxides, titanium oxide is also resistant to strong bases such as concentrated NaOH. This thin surface oxide is also a highly effective barrier to hydrogen.
