The Raman spectra of geikielite (MgTiO3-ilmenite) have been recorded at high pressure (up to 27 GPa) and at high temperature (up to 1820 K). No phase transitions could be evidenced in both cases. In particular, no cation disordering can be evidenced from the high temperature spectra. The observed Raman wavenumber shifts with pressure and with …

Jan 31, 2019 · 1 Introduction. Crystallization models of the lunar magma ocean (LMO) indicate that after the formation of a primordial crust by plagioclase flotation, ilmenite-bearing cumulates (IBC) containing Ti-rich oxides form when 87–95 vol.% of the mantle has solidified (e.g., Elardo et al., 2011; Elkins-Tanton et al., 2011; Snyder et al., 1992).With a …

May 1, 2020 · Ilmenite has its own spectral signature, which is the absorption band near 1550 nm. This band is considered to be formed by a heterogeneous intervalence charge transfer Fe 2+ → Ti 4+ (Burns, 1993).The mechanism leading to the transfer is a delocalization of electrons between adjacent cations with the formation of a molecular …

Feb 9, 2012 · The direct electrochemical extraction of Ti-Fe alloys from natural ilmenite (FeTiO3) in molten CaCl2 is reported in this article. The sintered porous pellet of natural ilmenite acted as the cathode of the electrochemical system, and the carbon-saturated liquid tin contained in a solid-oxide oxygen-ion-conducting membrane (SOM) tube …

Dec 1, 2023 · The ilmenite and iREEs ores are hosted in the tonalite-derived regolith, with the ilmenite ore grade of 15–57 kg/m 3 and the iREEs ore grade of 500–900 ppm. Both the ilmenite and iREEs ore reserves have been proven on a large deposit scale ( Gao et al., 2013 , Jiang and Lu, 1997 , Wang, 1989 ).
For low-Ca activities, rutile may be stable down to 0.7 GPa (and below) within ilmenite pseudomorphs while the titanite stability field may extend to pressures >1.3 GPa for Ca-richer compositions. Both species may be stable in one single sample depending on the local Ca activity gradients. The finding of metamorphic rutile within metagranitoids ...
