Ilmenite
Ilmenite is a combined oxide naturally occurring in the form FeTiO3, which is also the reduced form in CLC. The oxidized form is Fe 2 TiO 5 + TiO 2. It has also been shown that there is a migration of Fe to the surface; thus in practice ilmenite is in part an iron oxide material ( Adanez et al., 2010 ).Web
