Titanium Dioxide (Titanium Oxide)
Definition - What does Titanium Dioxide (Titanium Oxide) mean?
Titanium dioxide is a naturally occurring chemical that has a white powdery appearance and is formed by the reaction of oxygen and titanium. The chemical formula for titanium dioxide is TiO2. It provides a high level of corrosion resistance on titanium surfaces due to the ease of passivation in oxidized environments where it forms a protective oxide film.
Titanium dioxide may also be known as titanium oxide.
Corrosionpedia explains Titanium Dioxide (Titanium Oxide)
When titanium reacts with oxygen to form titanium dioxide, it forms a passive oxide layer that makes it a remarkable corrosion resistant material.
Titanium dioxide is used to produce coatings for corrosion prevention, often in combination with anodic coatings due to variances in electrochemical parameters.
Titanium is found in abundance in the Earth's crust and is considered to be the fourth most abundant material. It usually occurs as an oxide ore.
In 1887, titanium was first extracted in the metallic form; however, it was impure. In 1910, it was extracted in the purest form. After the 1950s it has been used to manufacture titanium structures. Commercially, the important forms of titanium are titanium dioxide (rutile) and titanium iron oxide (ilmeite).
