Ilmenite - an overview | ScienceDirect Topics

The aluminothermic method for ferrotitanium processing is the most common (Gous, 2006). Reduction of titanium by aluminum from ilmenite and rutile proceeds via the formation of intermediate monoxide TiO (TiO x), which, as basic oxide, is able to form titanium aluminate. This decreases the activity of TiO and makes titanium recovery more difficult.
