Ilmenite Reduction Lunarpedia

May 02, 2013 Reducing ilmenite (FeTiO 3) to produce oxygen, iron, and titanium in a lunar context has produced a number of proposals, many of them specifically aimed at oxygen production. Ilmenite is attractive for this purpose as the iron oxides it contains require less energy to reduce than any other oxide on the lunar surface.

Ilmenite Wikipedia

Ilmenite is commonly recognized in altered igneous rocks by the presence of a white alteration product, the pseudo-mineral leucoxene. Often ilmenites are rimmed with leucoxene, which allows ilmenite to be distinguished from magnetite and other iron-titanium oxides. The example shown in the image at right is typical of leucoxene-rimmed ilmenite.

Ilmenite: An ore of titanium Uses and Properties

What is Ilmenite? Ilmenite is a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. Apollo astronauts found abundant ilmenite in lunar rocks and the lunar regolith. Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3.. Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys.

Effect of Sulfur on the Reduction of Ilmenite by Syngas in

Ilmenite can be reduced to different forms depending on the reaction gas composition, notably CO 2 in this case. Usually, when enough CO 2 is present, ilmenite reduction is limited to Fe 3 O 4 (RRR3 and RRR4), and when CO 2 is absent, ilmenite can be further reduced to FeO (RRR5 and RRR6) or even Fe (RRR7 and RRR8).
