A brief introduction to production of titanium dioxide and …
Ilmenite can also be converted to a more pure titanium dioxide product using the Becher process. This process consists of high-temperature exposure to oxygen in air to convert ilmenite to pseudobrookite: 4FeTiO 3 + O 2 = 2Fe 2 O 3 TiO 2 + 2TiO 2. The oxidation process oxidizes the iron and allows it to form a separate iron oxide phase.
