Ilmenite. Ilmenite is an iron-oxide mineral of the oxide and hydroxide group with structural formula (Fe,Ti)2O3. The structure is similar to that of hematite, where the two Fe3+ in hematite are replaced by one Fe2+ and one Ti4+ in ilmenite. It consists essentially of a dense arrangement of Fe2+ and Ti4+ ions in octahedral coordination with ...
