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

ON THE REACTIONS IN ILMENITE, ALUMINUM AND GRAPHITE SYSTEM
Iranian Journal of Materials Science and Engineering, 2016 Al2O3/TiC composites are used as cutting tools for machining gray cast iron and steels. The addition of iron improves the toughness of Al2O3/TiC composites.

Occurrence and Provenance of KREEP Components in Glassy Agglutinates From Chang'e‐5 Lunar Regolith
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract This study investigates the petrogenesis of glassy agglutinates in a polished section of the Chang'e‐5 lunar regolith sample CE5C0800YJYX018GP through integrated petrographic, mineralogical, and geochemical analyses of four representative particles (18GP‐01 to 18GP‐04).

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.

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract Lunar magnetic anomalies are abundant near the south pole, where several moderate‐strength anomalies spatially overlap permanently shadowed regions (PSRs). This environment provides a unique setting to assess how crustal magnetic fields and topography regulate plasma–surface interactions and, in turn, the stability and distribution of surface ...

Characterization of electrical behavior in modified ilmenite
, 2013 Naturally-occurring Ilmenite ore is usually a mixture of Ilmenite (FeTiO3) and hematite (Fe2O3). Synthesized solid solutions of Ilmenite and hematite are known to have interesting magnetic and electric properties.

Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology
Journal of Metamorphic Geology, Volume 44, Issue 6, Page 417-439, July 2026.ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

On placer ilmenite composition [PDF]
, 1982 A selected pure sample of fresh ilmenite was examined by activation analysis technique to study its complete chemical composition. The method produced a very wide spectrum which cannot be obtained by any other methods.

Journal of Metamorphic Geology, Volume 44, Issue 6, Page 440-469, July 2026.ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with
