Characterization of lunar ilmenite resources

, 1989
Ilmenite will be an important lunar resource, to be used mainly for oxygen production but also as a source of iron. Ilmenite abundances in high-Ti basaltic lavas are higher (10--20%) than in high-Ti mare soils (mostly

Magnetite-rutile symplectite derived from ilmenite-hematite solid solution in the Xinjie Fe-Ti oxide-bearing, mafic-ultramafic layered intrusion (SW China)

, 2015
A unique symplectitic intergrowth of magnetite + rutile is hosted by ilmenite in the gabbro of the Xinjie Fe-Ti oxide-bearing, mafic-ultramafic layered intrusion.

Carbothermal reduction and nitridation of ilmenite concentrates

, 2012
Carbothermal reduction and nitridation of ilmenite concentrates of different grades and synthetic rutile were studied in isothermal experiments in hydrogen – nitrogen gas atmosphere and pure nitrogen in a tube reactor. Concentrations of CO and CO2 in the

Shock compression of ilmenite [PDF]

, 1976
Single- and reflected-shock compression measurements on single-crystal ilmenite (FeTiO_3) to pressures of 635 and 930 kbar, respectively, demonstrate anomalously large compressions above ∼320 kbar and imply the onset of one or more major phase changes at

Effect of ilmenite and barite addition on gamma rays attenuation of cement pastes: study of the pore structure by positron annihilation technique

Journal of Infrastructure Preservation and Resilience
Designing cementitious composites that both withstand mechanical loads and provide effective γ-ray shielding requires understanding how high-density mineral fillers alter hydration, pore structure, and radiation attenuation—knowledge that is currently ...

Mechanically activated carbothermic reduction of ilmenite

, 1997
A systematic study of the effect of milling conditions on the low-temperature carbothermic reduction of the mineral ilmenite has been carried out. It was found that after ball milling of an ilmenite-carbon mixture at room temperature, the ilmenite was ...

Oxidation of Indian Ilmenite: Thermodynamics and Kinetics Considerations [PDF]

, 2006
Natural Ilmenite (FeO.TiO2) is the primary source for the extraction of titanium dioxide (T1O2). Oxidation-reduction process is used for production of synthetic rutile from ilmenite by separation of Fe-oxides from TiO2.

Getting Lunar Ilmenite: From Soils or Rocks

, 1989
Lunar soils or rocks can be mined as sources of ilmenite for producing oxygen. However, separable crystals of loose ilmenite in lunar soils are rare (
